Answer: Photosynthetic organisms take light energy and use it to make their own "food". In this process they use carbon dioxide and light to make sugars and oxygen. This is great for other animals that utilize this oxygen and eat the plants for food.

Answer:
Hertz (I guess you can say love HERTZ)
Explanation:
The hertz (image: Hz) is the determined unit of recurrence in the International System of Units (SI) and is characterized as one cycle for every second. It is named after Heinrich Rudolf Hertz, the principal individual to give definitive evidence of the presence of electromagnetic waves.
Since both elements have a +1 charge, they cannot lose or gain electrons to form a bond. Plus they are both metals, so it wouldn't form a natural bond
Your best answer for 1 is B.
Answer:
The molar mass of the gas is 90.4g/mol
Explanation:
To solve this question we have to use the equation:
d = PM / RT
<em>Where d is density of the gas = 2.29g/L</em>
<em>P is pressure = 0.75atm</em>
<em>M is molar mass of the gas = ??</em>
<em>R is gas constant = 0.082atmL/molK</em>
<em>T is absolute temperature = 88°C + 273.15 = 361.15K</em>
<em />
Solving for M:
dRT / P = M
2.29L*0.082atmL/molK*361.15K / 0.75atm = M
90.4g/mol = M
The molar mass of the gas is 90.4g/mol
