c. Water and base
b. Carbon and salt
d. Carbon dioxide and water
Answer: Option (a) is the correct answer.
Explanation:
When an acid reacts with a metal then there occurs formation of a salt along with liberation of hydrogen gas.
For example,
Here, Zn (zinc) is the metal which when added to hydrogen chloride acid them it leads to the formation of salt zinc chloride and hydrogen gas.
This type of reaction is also known as single displacement reaction.
Thus, we can conclude that salt and hydrogen is produced when an acid reacts with a metal.
Answer:
it would be OA that is negatively charged
The number of kilograms of fuel that are contained in one canister is 1.03 Kilograms
calculation
mass = density x volume
Density= 0.710 g/cm³
volume = 1.45 L
convert 1.45 l into cm³ to make the units uniform
that is 1 L= 1000 cm³
1.45 L= cm³
by cross multiplication
= (1.45 L x 1000 cm³) / 1 L = 1450 cm³
mass is therefore = 0.710g/cm³ x 1450 cm³ =1029.5 grams
convert grams to Kg
1 kg = 1000 grams
? kg =1029.5 grams
by cross multiplication
= (1 kg x 1029.5 grams) /1000 grams = 1.0295 Kg ≅1.03 kg
the canister contains a gas used to fuel a burner
the volume of the white gas to be used is - 1.45 L
density of white gas is 0.710 g/cm³
density is defined as the mass per unit volume
the mass of 1 cm³ of white gas is - 0.710 g
1 cm³ is equivalent to 0.001 L
the volume given is in Litres
so if 0.001 L has a mass of 0.710 g
then 1.45 L have a mass of - 0.710 g / 0.001 L x 1.45 L = 1030 g
since 1000 g is equivalent to 1 kg
mass of white fuel is - 1030 g/1000 g/kg = 1.03 kg
theres 1.03 kg of fuel in one canister
Answer:
The reaction would be 1500n (equal reaction)
Explanation:
This can be explained by Newton's third law of motion which states that for every action (force), there is an opposite and equal reaction. In other words, when two objects or people come in contact, the magnitude of force which they exert on each other is equal and they both feel an equal reaction force.
It doesn't matter whether one of the colliding bodies is of bigger mass than the other. This Newton's third law of motion is also known as the law of action and reaction.
The DNA or deoxyribonucleic acid is composed of a pentose sugar, a base and phosphate group. The bases are adenine, thymine, cytosine and guanine. Guanine always forms hydrogen bonds with cytosine. Remember the statement “Apples in the Tree, Cars in the Garage”. The A stands for adenine and pairs with T-thymine then C – cytosine and G – guanine.
