Answer:

I say the 1st one I'm so terrible sorry if I'm wrong

Explanation:

Water can take many forms. At low temperatures (below 0°C), it is a solid. When at “normal” temperatures (between 0°C and 100°C), it is a liquid. While at temperatures above 100°C, water is a gas (steam).

The state the water is in depends upon the temperature.  Each state (solid, liquid, and gas) has its own unique set of physical properties.

Why does lowering the pressure cause a liquid to boil?
A. It becomes easier for molecules to escape.
B. It pushes molecules out of the liquid.
C. It causes the temperature to rise.
D. It changes the volume of the liquid.

Answers

Lowering the pressure in a container will cause the liquid in the container to boil faster because it becomes easier for the molecules to escape.

What causes boiling?

Boiling happens when the vapor pressure of a liquid equals the atmospheric pressure.

By lowering the atmospheric pressure, the vapor pressure of a liquid takes a lower time to equal the atmospheric pressure.

Thus, it becomes easier for the molecules of the liquid to escape from each other.

How many grams of gasoline were
burned if 1.63 x 1023 molecules of
water were produced? Only report
number (no units) and use correct sig
figs.

Answers

Answer:

31.0 g C8H18

Explanation:

Gasoline is equivalent to C8H18

to convert molecule to gram you have to convert molecules to mols first.

Using Avocado's number we can figure that out.

(1.63 x 10²³ molecules C8H18) (1 mol C8H18/ 6.022 x 10²³) = 0.271 mols C8H18

Then we convert mols to grams using the molar mass of C8H18

C - 8(12.011) = 96.088 g/mol

H - 18(1.008) = 18.144 g/mol

add that together: 114.232 g/mol

(0.271 mol C8H18) (114.232 g/ 1 mol C8H18) = 31.0 g

31.0 g C8H18

P.S: SORRY IF THIS DOESNT HELP!! I dont know if they are talking about the actual formula for gasoline.

For each of the following unbalanced equations indicate how many moles of the second reactant would be required to react exalt with 0.275 mole of the first reactant. Balance the equation.Co(s) + P4 (s) Co3P2 (s)

Answers

Answer:

0.183 mol

Explanation:

so balenced equation is 6Co+4P=2(Co3P2)

so so the ratio is 6:4

so .275/6*4

=0.183 mol I think

The Answer will be:  0.183 mol

 so that the balanced equation is 6Co+4P=2(Co3P2) When the ratio is 6:4

       so that .275/6*4

      =0.183 mol.

When According to the A balanced chemical is equation has been equal numbers of atoms that are for each element they are involved in the reaction and its represented on the reactant and its product sides.Also that This is a better requirement that makes the equation must be satisfied and also that to be consistent with the law of conservation of the matter. then It may occur that it is confirmed by simply summing the numbers of atoms and also molecules on it either side of the arrow and it's comparing these sums to ensure that they are equal.

One energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.

What is energy transformation?

Energy transformation is the process in which one form of energy converted into another form of energy.

What is photosynthesis process?

Photosynthesis process is defined as the process in which plants makes their own food by using the carbon dioxide, water and sunlight in the chlorophyll.

The balanced chemical equation of photosynthesis process is

6CO2 + 6H2O → C6H12O6 + 6O2.

Since, it have 6 atoms of carbon, 12 atoms of hydrogen and 18 atoms of oxygen on both side. So, it is balanced.

Since, sunlight which it take is in the form of radiant and convert it into chemical energy.

Thus, we concluded that the energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.

To prepare 800mL of 1M phosphate buffer of pH 7.2 (PKa=7.1), by using salt = K2HPO4 and acid = KH2PO4, the quantity of salt required is

Answers

Answer:

78.04g of 0.448 moles must be added

Explanation:

Using H-H equation we can find the pH of the buffer:

pH = pKa + log [A⁻] / [HA]

Where pH is the pH of the buffer = 7.2

pKa = 7.1

[A⁻] = [K₂HPO₄]

[HA] = [KH₂PO₄]

Replacing:

7.2 = 7.1 + log [K₂HPO₄] / [KH₂PO₄]

0.1 = log [K₂HPO₄] / [KH₂PO₄]

1.2589 = [K₂HPO₄] / [KH₂PO₄] (1)

And as the  concentration of the buffer is:

1M = [K₂HPO₄] + [KH₂PO₄] (2)

Replacing (2) in (1):

1.2589 = 1M - [KH₂PO₄] / [KH₂PO₄]

1.2589 [KH₂PO₄] = 1M - [KH₂PO₄]

2.2589 [KH₂PO₄] = 1M

[KH₂PO₄] = 0.44M

And [K₂HPO₄] = 0.56M

In 800mL = 0.8L:

0.8L * (0.56mol / L) = 0.448 moles K₂HPO₄. The mass is -Molar mass K₂HPO₄: 174.2g/mol-:

0.448 moles * (174.2g / mol) =
