Answer:
I thinks something bad will happen but science can change so im not sure
Explanation:
Science changes because of diffrent thing like enviorment
Answer:- Ca = +2, S = +6 and O = -2
Solution:- There are certain rules for oxidation numbers. As per the rule, oxidation number of alkaline earth metals in their compounds is +2.
Oxidation number of oxygen in it's compounds is -2(except peroxides) and the sum of oxidation numbers of all the elements of a neutral compound is zero.
Since, Ca is +2 and O is -2, the oxidation number of S could easily be calculated for the given compound as:
Let's say the oxidation number of S in 
is 
. Let's make the algebraic equation and solve it.
Hence. the oxidation number of Ca is +2, O is -2 and S is +6.
Answer: Relative humidity
Explanation:
Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor has higher relative humidity in cool air than in warm air. A related parameter to that regard is that of dew point.
Answer:
Explanation:
H = 1
C = 12
O = 16
Acetylene, HC≡CH = 2+24 = 26
H2O = 2 + 16 = 18
In XS oxygen, one HC≡CH yields one H2O
26 g HC≡CH ==> 18 g H2O
2000 g HC≡CH ==> 2000*18/26 g H2O = 1384.6154 g H2O
Answer:
Answer: 882mmHg
Explanation:
In a closed-end manometer, the gas added is under a pressure that is measured against atmospheric pressure. The difference in pressure between both gases is equal to the difference in mercury levels. Thus, the pressure of the argon can be:
783 mmHg - 96.0mmHg = 687mmHg
783 mmHg - 96.0mmHg = 879mmHg
Based on the options, the possible answer (The nearest to the second value) is:
<h3>Answer: 882mmHg</h3>
