To answer this problem, we must make assumptions for simplicity. The first assumption is that, the system only consist of these 3 gases. The second assumption is that, these gases behave ideally. Thus, from Dalton's Law of Partial Pressure, the total pressure is simply the sum of their individual partial pressures.
Total pressure = 2.5 + 0.8 + 3.4 = <em>6.7 atm</em>
Answer:
The substance (or substances) initially involved in a chemical reaction are called reactants or reagents. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants.
Explanation:
An electron has a relative mass of 0, whilst an alpha particle has a relative mass of 4
An electron has a relative mass of 0, whilst a proton has a relative mass of 1
A neutron has a relative mass of 1, whilst an alpha particle has a relative mass of 4
A neutron has a relative mass of 1, and a proton also has a relative mass of 1
Answer:
I think your answer is either b or c but I think b is more likely to be your answer
<h3>
Answer:</h3>
#a. 25.33 kPa
#b. 0.25 atmospheres
<h3>
Explanation:</h3>
- Pressure may be measured using several units which include pascals, atmospheres, mmHg and kilopascals.
- These units of measuring pressure may be converted from one unit to another using a conversion factor.
For example;
1 kPa = 7.5 mmHg
Thus, in our case,
#a. To convert 190 mmHg to kPa
we divide 190 mmHg by 7.5 mmHg
= 190 mmHg ÷ 7.5 mmHg
= 25.33 kPa
Hence, 190 mmHg is equivalent to 25.33 kilopascals
Another conversion factor is;
1 atm = 760 mmHg
Therefore, in our case,
#b. To convert 190 mmHg to atmospheres
we divide 190 mmHg by 760 mmHg
That is; 190 mmHg ÷ 760 mmHg
= 0.25 atm
Thus, 190 mmHg is equivalent to 0.25 atm
