Answer:
Sunlight provide light energy.
Chlorophyll absorb light.
Explanation:
Sunlight provide light energy or give light energy from sun and it is use to produce glucose from carbondioxide and water which is also a source of energy.
Chlorophyll absorbs light energy and use it to convert carbondioxide and water into glucose and oxygen or it captures sun rays and produce glucose and water.
Answer:
0.67 L
Explanation:
Given data:
Volume of carbon dioxide = ?
Mass of nitroglycerine = 2.5 g
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Solution:
Chemical equation:
4C₃H₅N₃O₉ → 12CO₂ + 10 H₂O + 6N₂ + O₂
Number of moles of nitroglycerine:
Number of moles = mass/ molar mass
Number of moles = 2.4 g/ 227.1 g/mol
Number of moles = 0.01 mol
Now we will compare the moles of nitroglycerine and carbon dioxide from balance chemical equation.
C₃H₅N₃O₉ : CO₂
4 : 12
0.01 : 12/4×0.01 = 0.03 mol
Volume of CO₂:
PV = nRT
V = nRT/P
V = 0.03 mol× 0.0821 atm.L/mol.K× 273.15 K / 1 atm
V = 0.67 L
Answer:
Metals have high densities, high melting points, are malleable and ductile, and can conduct heat and electricity.

Answer:
CCl₂
Explanation:
Let us calculate the mass of carbon present in 100 grams of sample.
The formula to calculate the mass of carbon we can use the following formula.
The mass of chlorine in the sample = 100-14.5 = 85.5g
Let us calculate the moles of each element:
moles of carbon = 
Moles of chlorine = 
The mole ratio is :
C:Cl = 1.208:2.41 = 1:2
So the empirical formula of the compound must be CCl₂
<span>An insect would have an easier time walking on the surface of water than on the surface of ethanol. Water's stronger intermolecular forces lead to higher surface tension. Higher surface tension allows water to support the insect. I hope this helps.</span>
