Answer: metal and carbonate
Explanation:
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions 
when dissolved in water and an acid is defined as a substance which donates hydrogen ions 
in water.
An acid is represented as :
1. When metal is treated with an acid such as 
, if the metal is more reactive than hydrogen displaces hydrogen from its salt solution and thus produce zinc chloride and hydrogen gas.
2. When carbonates are treated with acid, double displacement takes place ad carbon dioxide is released as a gas.
Ti2 has 2 unpaired electrons.
That what I found 0.1 M NaCl
Answer:
Given,
P1=760 torr
T1=21°C
T2=250°C
P2=?
Solution,
According to Gay-Lussac's Law or Third Gas Law,
P1T2=P2T1
760×250=21×P2
P2=9047 torr
9047 is the pressure of the gas at 250 degree Celsius.
Answer:
grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
Explanation:
The molecular weight of acetylene is 26.04 g/mol
Molecular weight of carbon is equal to 12.011 g/mol
Two carbon atom produces one acetylene molecule.
Thus, 2 * 12.011 g/mol of carbon is used to produce 26.04 g/mol of acetylene,
Amount of carbon required to produce 59.8 grams of acetylene
grams/mol
grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
