Answer: convalent compounds share two elements in forming a BOND between atoms
Explanation: if you dont believe me look it up and google will give you the same answer
please give brainliest
We have M1V1=M2V2. Here M1 is to be found, V1=25ml=(25/1000)L &
M2=1.0M, V2=18ml=(18/1000)L.
Therefore M1=(M2V2)V1
so after putting values we get answer 0.72M.
Hope it helps.
Answer:
78.14 % B; 21.86 % H
Step-by-step explanation:
The formula of diborane is B₂H₆.
The masses of each element are:
2B = 2 × 10.81 = 21.62 u
6H = 6 × 1.008 = <u> 6.048 u
</u>
TOTAL = 27.67 u
% B = 21.62/27.67 × 100
= 78.14 %
% H = 6.048/ 27.67
= 21.86 %
As the water is heated, c. the kinetic energy of the water molecules increases. Kinetic energy is the energy caused by an object's motion. This means that water molecules tend to move faster when heated. This is related to its temperature increase, as temperature is directly proportional to kinetic energy.
Answer:
31.37%
Explanation:
For this case, you should consider the following reaction:
Ba⁺²₍aq₎ + H₂SO₄ ₍aq₎ → BaSO₄ ₍s₎ + H₂O
For which you obtain the precipitate of BaSO₄
In order to obtain the mas of Barium on the precipitate, you may use the following formula:
gBa= M₍BaSO₄₎x(M₍Ba₎/M₍BaSO₄₎)
Where:
gBa= mass of Barium
M₍BaSO₄ ₎= mass of BaSO₄ from the precipitate
M₍Ba₎= mass of Barium from the original sample
M₍BaSO₄₎= mass of BaSO₄ from the precipitate
gBa= (0.5331)x(137.327/233.39)= 0.3136 g
Then we ontain the percentage of Barium multiplying by 100:
% Ba on the original sample= 31.36%
