Answer:

${ \underline{ \sf{O _{2} \: is \: reduced}}}$

Explanation:

Reduction means when a reactant loses oxygen or gains hydrogen.

In the equation:

Hydrogen molecule, it neither gains nor loses hydrogen, but it gains oxygen. so :

${ \sf{H _{2} \: is \: excluded}}$

Oxygen molecule loses one oxygen atom, and gains four hydrogen atoms, hence it is reduced.

The churning air in the troposphere helps determine the of a place

Arturiano [62]

The answer is the climate of a place. The troposphere is the lowermost level of Earth's air, and is likewise where closely all weather and climate situations happen. It covers about 75% of the air's mass and 99% of the total form of water vapor and aerosols.

How many milliliters (mL) are in 0.847 liters (L)

alex41 [277]

Answer:

847 mL

Explanation:

Step 1: Find conversion

1 L = 1000 mL

Step 2: Use Dimensional Analysis

$0.847 \hspace{2} L(\frac{1000 \hspace{2} mL}{1 \hspace{2} L} )$

<em>We see that Liters and Liters cancel out, so we simply multiply.</em>

847 mL

A 975 L balloon contains helium. On the ground the temperature is 30 0C and the pressure is 743 torr. What will be the balloon's

Archy [21]

Answer:

V₂ = 1518L

Explanation:

-Using combined gas law:

$\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}$

<em>Where P is pressure, V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.</em>

<em />

<em>Initial states:</em>

P₁ = 743 torr

V₁ = 975L

T₁ = 30°C + 273.15K = 303.15K

P₂ = 375 mmHg = torr

V₂ = Our incognite

T₂ = -35°C + 273.15K = 238.15K

Replacing:

$\frac{743torr*975L}{303.15K} =\frac{375torrV_2}{238.15K}$

Which monomer gives a greater yield of polymer, 5-hydroxypentanoic acid or 6-hydroxyhexanoic acid? Explain your choice.

LekaFEV [45]

Answer:

6-hydroxyhexanoic acid

Explanation:

5-hydroxypentanoic acid will form a 7 member group, while 6-hydroxyhexanoic acid will form a 6 member group.

In polymerization, polymers with 6 member groups are more stable than the ones with 7 member groups. This means that 6-hydroxyhexanoic acid will have a higher chance of polymerization, and therefore give a greater yield of polymers, than 5-hydroxypentanoic acid.
