Answer:

which formula can be used to calculate the molar mass of hydrogen peroxide (H2O2)?

» d.2 x molar mass of H + 2 x molar mass of O

Explanation:

Since we've two hydrogen atoms and two oxygen atoms, we multiply each mass by 2

$= (2 \times hydrogen) + (2 \times oxygen) \\ = (2 \times 1) + (2 \times 16) \\ = 2 + 32 \\ = 34 \: g$

a].When sand is added to water it either hangs in the water or forms a layer at the bottom of the container. Sand therefore does not dissolve in water and is insoluble. It is easy to separate sand and water by filtering the mixture.

b]. The water filtered by kamal is not safe to drink .

If you run out of water, or cannot carry enough water with you for your entire trip, you may need to source drinking water from natural water sources.

Answer:

625=275

240=x

625x=275×240

625x=66000

x=66000/625

x=105 .6

Explanation:

If 625°C gives us 275KPa then 240°C will give us the the sum of 275×240 divided by 625

15% by volume of blood your brain gets at rest. Your body contains 5.2 L of blood, how many liters of blood are in your brain at

REY [17]

Answer: 0.8242182 quarts of blood will be present in the brain at rest.

Solution:

According to question: 15% by volume of blood your brain gets at rest

if we are having 5.2 L of blood in our body , then blood present in our brain at rest:

$15\%\text{of the 5.2 L of blood}=(5.2 L)\times \frac{15}{100}=0.78 L$

if 1 L= 1.05669 quart

Then 0.78 L will be =0.78 L $\times$ 1.05669 quart = 0.8242182 quarts

0.8242182 quarts of blood will be present in the brain at rest.
