help me please !! is it A,B,C, or D ???

Answers

Ok, after doing an immense amount of research I came up with the most logical answer.

A. Is indicated by a negative enthrall sign.

Reasoning: an endothermic reaction is ice melting and the energy being more than its surroundings. Not specified to ice but as an example, ice is endothermic. That puts d and b out of the running leaving you left with a and c.

When I searched up enthalpy, it said “When a substance changes at constant pressure, enthalpy tells how much heat and work was added or removed from the substance.” Which is similar to c, right? Yeah, meaning both a and c are similar in that aspect.

The reason I decided to go with a is because heat is NOT released into the surrounding, exothermic reactions release energy and heat into the surrounding.

Explanation:

how many moles of Fe(OH)2 are required to produce 7.4 moles of Fe3(PO4)2

Answers

Answer:

22.2 mol

Explanation:

Considering the reaction stoichiometry, 22.2 moles of Fe(OH)₂ are required to produce 7.4 moles of Fe₃(PO₄)₂.

The balanced reaction is:

3 Fe(OH)₂ + 2 H₃PO₄ → Fe₃(PO₄)₂ + 6 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Fe(OH)₂: 3 moles H₃PO₄: 2 molesFe₃(PO₄)₂: 1 mole H₂O: 6 moles

Then you can apply the following rule of three:  if by reaction stoichiometry 1 mole of Fe₃(PO₄)₂ requires 3 moles of Fe(OH)₂, 7.4 moles of Fe₃(PO₄)₂ require how many moles of Fe(OH)₂?

[tex]amount of moles of Fe(OH)_{2} =\frac{7.4 moles of Fe_{3} (PO_{4} )_{2} x3moles of Fe(OH)_{2} }{1mole of Fe_{3} (PO_{4} )_{2} }[/tex]

amount of moles of Fe(OH)₂= 22.2 moles

Finally, 22.2 moles of Fe(OH)₂ are required to produce 7.4 moles of Fe₃(PO₄)₂.

1375 J of heat energy are added to a 50.0 g sample of copper, which increases temperature from 22.8 C to 94.2 C. Calculate the specific heat of copper.

Answers

Answer:

0.385 J/g°C

Explanation:

Using the following formula, the specific heat of an elemental substance can be calculated:

Q = m × c × ∆T

Where;

Q = quantity of heat (J)

m = mass (g)

c = specific heat capacity (J/g°C)

∆T = change in temperature (°C)

Based on the given information, Q = 1375J, m = 50g, initial temperature = 22.8°C, final temperature = 94.2°C, c =?

Q = m × c × ∆T

1375 = 50 × c × (94.2 - 22.8°C)

1375 = 50 × c × 71.4

1375 = 3570c

c = 1375/3570

c = 0.3851

c = 0.385 J/g°C

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

The loosening of soil and they bind the soil with the help of the roots

Explanation:

Here, we want to know how plants prevent erosion by wind or water.

The way they do this is by binding the soil with their roots such that it will not be easy for the erosion agent to erode the surface.

How they do this is by making sure that the soil

particles are binded together with their roots which helps to keep the particles of the soil intact and not eroded

20 mL of a gas at 200K is heated until the new volume is 55 mL. What is the final temperature of the gas?

answer options:
4.0 K
5.5 K
400K
550 K

Answers

Answer:

550 K

Explanation:

Given the following data;

Original Volume, V1 = 20mL

Original Temperature, T1 = 200K

New Temperature, V2 = 55mL

To find new temperature T2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

[tex] VT = K[/tex]

[tex] \frac{V1}{T1} = \frac{V2}{T2}[/tex]

Making T2 the subject of formula, we have;

[tex]T_{2} = \frac{V2}{V1} * T_{1}\\[/tex]

Substituting into the equation;

[tex]T_{2} = \frac{55}{20} * 200\\T_{2} = \frac{11000}{20}\\T_{2} = 550K[/tex]

Therefore, the new temperature is 550K.

What is the name and formula of an ionic compound containing the element with the
atomic number of 5 bonded to Carbonate? *
Boron Carbonide; B2(CO3)3
Boron Carbonate; B,CO,
Boron Carbide; B,CO,
Boron Carbonate; B2(CO3)3

Answers

Answer:

Boron Carbonate; B₂(CO₃)₃

Explanation:

For names, carbonide does not exist; that rules out the first option. Carbide refers to just a carbon atom, not carbon and oxygen as in the polyatomic ion carbonate. That rids us of the third option. We are left with boron carbonate with the formula BCO or boron carbonate with the formula B₂(CO₃)₃.

Recall the carbonate polyatomic ion's formula: CO₃²⁻

Thus BCO cannot be the formula.

Option 4 is your answer, Boron Carbonate; B₂(CO₃)₃.

To further check your answer, observe the oxidation states of boron and the polyatomic ion carbonate. Boron can exist in oxidation states of either 2+ or 3+, and carbonate is only 2-; in this formula, boron will exhibit a 3+ state to balance out with carbonate.

2x3+ = 6+; 3x2- = 6-

6+ + 6- = 0; balanced

Which air is driest? Air Temp 30F Dew-point 29F, Air Temp 77F Dew-point 19F, Air Temp 66F Dew-point 60F, or Air Temp 50F Dew-point 36F

Answers

Answer:

Air Temp 77F Dew-point 19F

Explanation:

Quiz

The dew point can be described as the temperature required by the air to be cooled. The driest air will have a higher dew point, therefore, at an air temperature of 66°F and a dew point of 60°F. Therefore, option (C) is correct.

What is dew point?

The dew point can be defined as the temperature at which air should be cooled to become saturated with water vapor assuming constant air pressure and water content.

Moisture capacity will decrease below the dew point. Airborne water vapor will condense to form liquid water or dew. Dew develops on the surface and occurs through contact with a cooler surface.

The dew point is called the frost point when the temperature is below the freezing point because frost is produced by deposition rather than a condensation of water.

The humidity also impacts the dew point. The dew point increases when there is higher moisture in the atmosphere.  Therefore, the higher dew point refers to less humid air or drier.

Answers

Answer:

Explanation:

The water is best classified as a compound. When a substance is broken down into elemental composition or units, they are said to be a compound.

An element is a distinct substance that cannot be split up into simpler substances. Compound are substances composed of two or more kinds of atoms  joined together in a definite grouping. The properties of compounds are distinct and different from those of the individual elements that are combined in its make - up. So, the water when broken down to elements is a compound.

2. Platinum metal has a density of 21.4 g/mL. If the block measures 3 cm, by 0.03 m, by 40 mm
how much does it weigh in milligrams?

Answers

Answer:

80mg

Explanation:

Given parameters:

Density of Platinum metal = 21.4g/mL

Dimension of the metal  = 3cm by 0.03m by 40mm

Unknown:

Weight of the metal in milligrams?

Solution:

Density is the mass per unit volume of a substance.

Mathematically;

          Density  = [tex]\frac{mass}{volume}[/tex]

Volume of the platinum metal  = l x w x h

 Let us convert the dimension of the metal to the same unit;

            3cm x 0.03m x 40mm

    convert to cm;

           100m = 1cm

           0.03m  = [tex]\frac{0.03}{100}[/tex]   = 0.0003cm

     -- 40mm;

            1mm = 0.1cm

           40mm  = 40 x 0.1  = 4cm

Volume of the metal  = 3 x 0.0003 x 4  = 0.0036cm³

1mL = 1cm³; so volume  = 0.0036mL

     Mass of the metal  = 21.4 x 0.0036  = 0.08g

       1g  = 1000mg

     0.08g  = 0.08 x 1000 = 80mg
