Answer:
Yes
Explanation:
It does because of the fact that plants need water to live and the grow. Water helps the plant grow, and certain plants would need less or more water based on their roots, leaves, and tempurature tolerancy.
No, it won't change the amount of reactants nor the products as a catalyst will only provide an alternative path where lower activation energy is needed for the process to take place.
hope this explains it
If it does, please give it a brainliest :)))
Answer:
0.705 g/cm³
Explanation:
Step 1: define density
The (volumetric mass) density of a sample or substance, is this sample or substance its mass per unit volume and can be defined through following formula:
ρ = m/v
with ρ = density (kg/m³)
m = mass of the substance (kg )
v = volume (m3)
Step 2: change datat SI-units
10.0 cm³ = 10^-5 m³
7.05 g = 0.00705 kg
ρ = 0.00705 kg / 10^-5 m³ = 705 kg / m³
To convert this to g/cm³ we have to divide by 1000
ρ = 0.705 g/cm³
To control this we calculate 7.05g / 10cm³ = 0.705 g/cm³
The desnity of the alcohol is 0.705 g/cm³
