You get something called hyporthostatoc drop in pressure that causes lightheaded and dizziness fainting can occur or can total shock to the body systems when the brain and heart and vital organs experience that kind of mixture in it

When temperature increases, you can think of it as ‘adding’ to the reactant of heat energy, meaning that the system will shift to the right.

Similarly, when temperature decreases, you are decreasing the concentration of the ‘heat energy’, meaning the reaction will shift to the left.

1. Which sample contains a total of 9.0 * 10 ^ 23 atoms ? A) 0.50 mole of HCI B) 0.75 mole of H 2 O C) 1.5 moles of Cu D) 1.5 mo

Alchen [17]

c. 1.5 moles of Cu will contain a total of 9.0 * 10 ^ 23 atoms.

Explanation:

To convert moles into atoms, the molar amount and number of atom is multiplied by Avagadro's number.

Avagadro's number is 6.022× $10^{23}$

So applying the formula in the given sample:

A) 0.5×6.022× $10^{23}$

3.01× $10^{23}$ atoms.

B) 0.75 mole of H20

O.75×6.022× $10^{23}$

= 4.5166× $10^{23}$ atoms.

C) 1.5 moles of Cu

1.5×6.022× $10^{23}$

= 9.033× $10^{23}$

D). 1.5 moles of H2

1.5 × 2 × 6.022 × $10^{23}$

= 18.066 × $10^{23}$ atoms because H2 is 2 moles of hydrogen.

Atom is the smallest entity of matter having property of the element to which it is a part.

A 5.5 g sample of a substance contains only carbon and oxygen. Carbon makes up 35% of the mass of the substance. The rest is mad

Mamont248 [21]

Answer:

The correct answer is option (1).

Explanation:

Mass of the sample = 5.5 g

Percentage of carbon in sample = 35 %

Percentage of oxygen in sample = 100% - 35%

$\%=\frac{\text{Mass of the element in the sample}}{\text{Mass of sample}}\times 100$

Mass of carbon in a sample: (35%) of 5.5 g

$\frac{35}{100}\times 5.5 g=1.925 g$

Mass of oxygen in a sample: (100%-35%) of 5.5 g

$\frac{100-35}{100}\times 5.5 g=3.575 g$
