Answer:
The greater the force that is applied to an object, the greater the acceleration. However, if that same force was applied to an object with a larger mass, it will have a smaller acceleration.
Explanation:
f=ma
Answer is:
It is likely soluble in water.
It will likely light up a bulb in a conductivity apparatus (CaO(l)).
It will likely have a high melting point.
1) Calcium oxide (CaO) has ionic bonds between calcium cations (Ca²⁺) and oxygen anions (O²⁻). It reacts with water and form calcium hydroxide:
CaO(s) + H₂O(l) → Ca(OH)₂(aq).
2) Ionic solid calcium oxide dissolved in water conduct electricty due to the dissociation Ca(OH)₂(aq) → Ca²⁺(aq) + 2OH⁻(aq).
3) Because it has strong ionic bonds, it has high melting point (around 2600°C).
Energy is extremely useful
As humans have always used energy, in the ancient times it was really only thermal, from burning wood for warmth and preparing food, then people learned to use animal's energy, and things moved on from there, getting into more complex stuff like we have today.
Life without energy from various sources is unimaginable today
Answer : 9773 kJ
Explanation:
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and 
for the reaction comes out to be negative.
To calculate the moles :
Given : Change in enthalpy on combustion of 1 mole of methanol = -1278 kJ
According to stoichiometry :
1 mole of methanol produce energy = 1278 kJ
Thus 7.647 moles of methanol produce energy =
Thus 9773 kJ of energy is produced from burning 245.0 g of methanol in excess oxygen
I believe the correct answer from the choices listed above is the third option. Scientists who possess honesty always report their observations and results truthfully. It <span> connotes positive and virtuous attributes such as integrity, truthfulness, straightforwardness. Hope this answers the question.</span>
