Answer:

Natural BGH and rBGH both increase the level of another hormone called insulin-like growth factor (IGF-1) in the cow.

Beef cattle are often given steroids to increase and speed growth. Common steroids include:

Major groups such as FDA and Food and Agricultural Organization state track level of hormones in food. They state that the levels of hormones in food are safe to eat. Not everyone agrees.

Explanation:

Hormones are present in all animal products. Some are natural, others may be added through supplements. Hormones and steroids are given to livestock. It can increase the number of dairy products and beef.

FDA establishes the acceptable safe limits for hormones in meat. A safe level for human consumption is a level of drug in the meat that would be expected to have no harmful effect in humans based on extensive scientific study and review.  

Answer:

It is becoming more acidic.

Explanation:

The pH scale is a way to express the concentration of hydrogen ions. This scale goes from 0 to 14 and it is adimensional.

The lower the pH, the more acidic the solution. Since the pH of the garden soil of Olivia is decreasing, it is becoming more acidic.

Answer:

Malleability is intensive

Length is extensive

Hardness is intensive

Volume is extensive

Explanation:

Extensive properties change when u change the size of an object and intensive properties don’t

Also I just took the quiz

A physical property refer to the properties of an object that can be measured and observed without changing (altering) the chemical composition of the object.  

In Chemistry, there are two (2) main types of physical property and these include:

I. Extensive property: this is a property that changes when the size of an object changes. Some examples of an extensive property are:

II. Intensive property: it is a property that remains the same regardless of the change in the size of an object, Some examples of an intensive property are:

Answer:

Explanation:

Iron(III) oxide gets mixed with elemental carbon and heated to make elemental iron and carbon dioxide.

2Fe₂O₃   +    3C    =    4 Fe   +    3 CO₂

2 x 160       3 x 12       4 x 56

320 gram of iron ( iii ) oxide requires 36 g of carbon for reduction

1 kg of iron will require 36 / 320 g of carbon

carbon required = 36 / 320 g

= .1125 g

= .113 g rounding off to 3 significant fig .

b )

320 gram of iron ( iii ) oxide produces  224  g of iron  after  reduction

1 g of iron will produce 224 / 320 g of iron

iron produced = 224 / 320 g

= 0.700 g .

Answer:

(a) Dissolving sugar in water  ⇒ physical change

(b) Crushing rock salt  ⇒ physical change

(c) Burning sulfur  ⇒ chemical change

(d) Digesting a chili dog ⇒ chemical change

Explanation:

Physical changes are those in which the substance does not alter its composition. They only involve changes of states of  matter and the chemical substance is stil the same after the change occurs. By other hand, chemical changes are those in which new subtances are formed. So, the subtance is not the same after the change.

(a) Dissolving sugar in water  ⇒ physical change; because we obtain a solution of sugar in water (sugar is stil sugar).

(b) Crushing rock salt  ⇒ physical change; because we obtain crushed salt, but the chemical composition of the salt is not altered.

(c) Burning sulfur  ⇒ chemical change; because sulfur is oxidized (chemical reaction) and new compounds are formed, for example sulfur dioxide.  

(d) Digesting a chili dog ⇒ chemical change; because the digestion process is produced by the action of hydrocloric acid, and new compounds are formed.

Answer : The kinetic energy will be 24 J.

Explanation : Given,

Mass of marble = 3 kg

Velocity of a marble = 4 m/s

Formula used to calculate the kinetic energy is:

[tex]K.E=\frac{mv^2}{2}[/tex]

where,

K.E = kinetic energy

m = mass

v = velocity

Now putting all the given values in this formula, we get:

[tex]K.E=\frac{3kg\times (4m/s)^2}{2}[/tex]

[tex]K.E=24kg.m^2/s^2=24J[/tex]            [tex](1J=1kg.m^2/s^2)[/tex]

Therefore, the kinetic energy will be 24 J.

Answer:

NH₃

Explanation:

The hydrogen bond is a specially strong type of dipole-dipole interaction. For a hydrogen bond to occur, a molecule must have a hydrogen atom and a very electronegative atom, such as nitrogen, oxygen or fluorine. The hydrogen atom has a positive charge density while the heteroatom has a negative charge density.

Answer:

SO3(g) + H2O(l) ------> H2SO4(aq)

Explanation:

'Redox' is a term used to describe reduction and oxidation since the both are complementary processes, one can not occur without the other.

A redox reaction is one in which there is a change in the oxidation number of the reactants from left to right of the reaction equation.

If we looks at the reaction;

SO3(g) + H2O(l) ------> H2SO4(aq)

There was no change in the oxidation numbers of species from left to right of the reaction equation. For instance, the oxidation state of sulphur is +6 on both sides of the reaction equation hence it is not a redox reaction.

Answer:

See explanation

Explanation:

The ability of a hydride to act as a reducing agent depends on the electro negativity of the central atom in the complex hydride anion.

If we compare the electronegativities of Boron and Aluminum, Boron is more electronegative than aluminum. The more electronegative the central atom is, the lesser the electron density on the hydride and the lesser its ability to act as a reducing agent.

For the reason stated above, LiAlH4, having aluminium of low electro negativity as its central atom is a better reducing agent than NaBH4.

Answer:

68.97g of milk must be added

Explanation:

To solve this problem we need to use the equation:

Q = C*m*ΔT -Coffee cup calorimeter equation-

This equation relates mass and change in temperature with heat of solution, Q.

The energy that decreases in the milk is the same that increases in the milk. That is:

Q(milk) = Q(tea)

Using the equation:

4.184J/molK* Mass milk * (65.0°C - 7.00°C) = 4.184J /molK * 200g (Tea) * (85.0°C - 65.0°C)

Mass milk * 58.0°C = 200g * 20.0°C

Mass milk = 4000g°C / 58.0°C

Mass milk =

Answer:

3-methylthiophene > thiophene > benzene > 2-methylfuran

Explanation:

Primarily, five membered heterocyclic aromatic rings undergo nitration at carbon-2. This is because, nitration at carbon-2 leads to the formation of three resonance structures while attack at carbon-3 yields only two resonance structures, hence it is less stabilized.

The presence of a methyl group which donates electrons promotes the stabilization of the cation formed in the nitration of 3-methylthiophene.

2-methylfuran is the least reactive towards nitration because the 2-position has been blocked by a methyl group.

Explanation:

The reaction can be done by adding the cations and the anions.

The binary compounds are always formed by the two different elements.

When one calcium ion, [tex]$ Ca ^{2+} $[/tex] combines with the two calcium ions, [tex]$ Cl^-$[/tex], they formed a binary compound of [tex]$ CaCl_2$[/tex].

When one [tex]$ Ca ^{2+} $[/tex] combines with one [tex]$S^{2-}$[/tex] ion, they formed CaS binary compound.

When one chromium ion [tex]$ Cr^{4+}$[/tex] combines with four ions of chlorine, [tex]$ Cl ^- $[/tex], the compound formed is [tex]$ Cr Cl_4$[/tex].

When 1 ion of [tex]$ Cr^{4+}$[/tex] combines with 2 ions of sulphur, [tex]$S^2$[/tex], the binary compound formed is [tex]$ CrS_2$[/tex].

Answer:

3 mL

Explanation:

1 cubic centimeter (cm³) is equal to 1 milliliter (mL).

We want to find out how many milliliters 3 cm³ is equal to.

Since 1 cm³ is equal to 1 mL, 3 cm³ is equal to 3 mL.

The quantity of 3.00 cm³ is the same as 3 milliliters (mL).

Answer:

27 or [tex]3.00^{3}[/tex] (they're the same)

Explanation:

Therefore, 27 cm is the same as 27 mL.

Given :

Number of heart beat in 1  minute , n = 70 .

The individual lives for 85 years .

To Find :

The number of heartbeats in their lifespan .

Solution :

Now , number of minutes in one hour is 60 .

One day contains 24 hours .

Therefore , minutes in one whole day :

[tex]24\times 60 = 1440\ sec[/tex]

Now , 1 year contains 365 days .

( Note : We are not considering any leap years )

Minutes in one year are :

[tex]365\times 1440=525600=5.25\times 10^5\ sec[/tex]

So ,total minutes in 85 years is :

[tex]=5.25\times 10^5\times 85\\\\=4.46\times 10^7\ sec[/tex]

Hence , this is the required solution .
