Don't take my word for it but I think it is
1: proteins
2: energy from the sun, carbon dioxide, and water
3: this one is confusing me but I think it would be nutrients from food and oxygen
4: water
Again these are attempts I can't prove these
Answer:
Ice
Explanation:
When ice melts it makes water
Answer:
4.767 grams of KCl are produced from 2.50 g of K and excess Cl2
Explanation:
The balanced equation is
2 K+ Cl2 --->2 KCI
Here the limiting agent is K. Hence, the amount of KCl will be calculated as per the mass of 2.50 gram of K
Mass of one atom/mole of potassium is 39.098 grams
Number of moles is 2.5 grams =
So, 2 moles of K produces 2 moles of KCL
0.064 moles of K will produces 0.064 moles of KCl
Mass of one molecule of KCl is 74.5513 g/mol
Mass of 0.064 moles of KCl is 4.767 grams
Answer:
0.11 nm
Explanation:
1.1 x 10-10 m
The goal is to convert the atomic radius from meters (m) to nanometres (nm). We do this by multiplying the value by 10^9.
This is given as;
The balloon must be heated to a temperature of 150 °C in order to have a volume of 6.00 L.
<h3>How are volume and temperature of gases related?</h3>
The volume of a gas is directly proportional to the temperature of the gas.
According to Charles' law: V1/T1 / = V2/T2
V1 =4.0 L
T1 = 9°C = (273. + 9) K = 282 K
V2 = 6.0 L
T2 = ?
T2 = V2×T1/V1
T2 = 6 × 282 / 4 = 423 K
423.2 K = 423 -273 = 150 °C
Therefore, the balloon must be heated to a temperature of 150 °C in order to have a volume of 6.00 L.
