The density of liquid mercury is 13.6 g/mL. What is the mass of a 175 mL sample of mercury?
Answer:
The answer is
2380 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
density of mercury = 13.6 g/mL
volume = 175 mL
The mass of the metal is
mass = 13.6 × 175
We have the final answer as
2380 gHope this helps you
Why are some isotopes radioactive and some are not?
Answer: there are atoms that either have too many or too few neutrons or protons in their nuclei. This results in an imbalance between the jedi forces holding them together, which leads to an excess of internal energy. Such atoms are said to be unstable or radioactive.
Explanation:
49.2 m = _________ hm
Mass = 35g Volume = 7cm³ What is the Density?
Answer:
The answer is
5.0 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass = 35 g
volume = 7 cm³
The density is
[tex]density = \frac{35}{7} \\ [/tex]

Why will a toy train remain still if you push on the engine with
A force of 3 N and your friend push on the caboose with a
Force of 3 N?
Explanation:
Because when two equal forces are applied from opposite directions, they "eliminate" each other.
The train would go right if a 3N force was only applied in the right direction, and it would go left if the same force was only applied to the left.
If a 3N force was applied to the right and a 2N force to the left, it would equal a 1N force to the right (3-2=1).
But there it's 3-3=0, so in practice the force is 0N. Therefore the train won't move.

A six row combin harvests 266 pounds of corn per min. How many bushels of corn does it harvest per hour? (Note: 1 Bu = 56 Lbs) Round to the nearest Whole Number.
Answer:
The six-row combin harvests 285 bushels of corn per hour.
Explanation:
The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.
If the relationship between the magnitudes is direct, you can apply the following formula:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{a*b}{c}[/tex]
In this case you can apply it in the following way: if 56 pounds is equal to 1 bushel, 266 pounds to how many bushels is it?
[tex]x=\frac{266 pounds*1 bushel}{56 pounds}[/tex]
x=4.75
This is, a six row combin harvests 4.75 bushels of corn per min.
So, being 1 hour equal to 60 minutes, you can apply the following rule of three: if in 1 minute a six-row harvester harvests , in 60 minutes how many bushels of corn it harvests?
[tex]bushels of corn=\frac{60 minutes*4.75 bushels of corn}{1minute}[/tex]
bushels of corn= 285
The six-row combin harvests 285 bushels of corn per hour.
standard units of measure for density
Answer:
g/cm³ for solids,
g/ml for liquids
g/L for gases.
Explanation:
Though SI unit of density is kg/m³, for convenience we use g/cm³ for solids, g/ml for liquids and g/L for gases. Mathematically, density is defined as mass divided by volume: ρ=m/V

4. What is the proper way to prepare an acid solution?
Answer:
Always add acid to a large volume of water. The solution may then be diluted with additional water to make one liter. You'll get an incorrect concentration if you add 1 liter of water to the acid.
An acid is concentrated solution hence, it should be added to considerable quantity of water. The required volume can then be adjusted by adding more water.
What are the properties of an acid?Acids form aqueous solution and have the property of electric conductivity. Acids reacts with other molecules by forming a covalent bond.
Acids are corrosive in nature, sticky to touch, tastes sour and have strong smell.
Acids can be qualitatively detected through litmus test. They turn blue litmus paper red. Their pH is < 7 on pH scale.
Acids can be classified as:
Strong acids - are the acids that dissociate in water completely.Weak acids - are the acids that partially dissociate in water.Chemically, acids can react with other metals, carbonates and bases. Common examples of acids are vinegar (acetic acid), hydrochloric acid (HCl), sulfuric acid (H2SO4) etc.
Acids are found in food items such as citrus fruits. Acetic acid is widely used in certain food preparations and as food preservative. Acids are commercially used in dyes, paints and in soft drinks.
Thus, acids are important in many chemical reactions.

If 5.0 g of copper cools from 35.0oC to 22.6 oC and loses 23.6 J of heat, what is the specific heat of copper? a. 0.038 J/(g. oC) b. 0.62 J/(g. oC) c. 0.076 J/(g. oC) d. 0.38 J/(g. oC)
Answer:
c = 0.38 J/(g-°C)
Explanation:
Given that,
Mass of copper, m = 5 g
Initial temperature, [tex]T_i=35^{\circ} C[/tex]
Final temperature, [tex]T_f=22.6^{\circ} C[/tex]
When copper cools, it looses 23.6 J of heat. We need to find the specific heat of copper. The heat lost is given by :
[tex]Q=mc\Delta T[/tex]
c is specific heat
[tex]c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{23.6}{5\times (22.6-35)}\\\\c=0.38\ J/g-^{\circ} C[/tex]
Hence, the correct option is d.
Describe how the charges of the subatomic particles interact with one another.
Answer:
Electrons, Protons, and Neutrons. ... Protons are another type of subatomic particle found in atoms. They have a positive charge so they are attracted to negative objects and repelled from positive objects. Again, this means that protons repel each other

Answer:
mitochondria and chloroplasts both have prokaryotic ribososmes
Explanation:
Mitochondria and chloroplasts are the modern descendants of early prokaryotic cells. These lived in primitive cells and later developed into part of them. This hypothesis is supported because both mitochondria and chloroplasts have their own primitive ribosomes. These two organs contain 70s ribosomes.What’s the first thing you should always do before starting a lab

This element has three fewer protons than oganesson 
Answer:
ununpentium
Explanation: this is element 115, Oganesson has 118
The atomic number of oganesson is 118. The element which is having three fewer protons than oganesson is moscovium (Mc) (115).
What is oganesson?
Oganesson is a newly found element synthesized in 2002 and is placed as 118'th element in the periodic table. In modern periodic table, the elements are arranged based on their atomic number.
Atomic number is the number of protons in the atom as well it is the number of electrons in the neutral atom. For a neutral atom the number of electrons are protons are equal.
Thus in a neutral atom the positive charges are neutralized by equal number of negative charges.
Thus, for 118'th element, there are 118 protons, three fewer from this means, there are 115 protons, the 115'th element in the modern periodic table is moscovium.
