Chemical bonds is what atoms are held together by
The gravitational attraction will be the weakest on the side of the Earth that is opposite the Moon.
Answer:
Initial velocity (u) = 0 m/s
Final velocity (v) = 60 m/s
Time (t) = 7 sec
Acceleration (a) = ?
a = (v-u)/t
a = (60-0)/7
a = 60/7
<u>a = 8.57 m/s²</u>
Answer:
1,1,1
decomposition reaction
Explanation:
The reaction equation is given as:
_Ca(OH)₂ → _CaO + _H₂O
This reaction is a decomposition reaction in which a single reactant breaks down to give two or more products.
To balance the equation, we assign variables a, b and c, then we use a mathematical approach to solve the problem;
aCa(OH)₂ → bCaO + cH₂O
Conserving Ca : a = b
O: 2a = b + c
H: 2a = 2c
let a = 1, b = 1 , c = 1
Answer:
A,B,E
Explanation:
A) Elements can't be physically separated.
B) Elements are indeed made of only one type of atom
E) Elements cannot be broken down into a simpler form, at least not without a ton of energy being released as an explosion :)
