Object A at 40 degrees C and object B at 80 degrees C are placed in contact with each other. The heat flow will flow from the Object B to the object A because of temperature difference. To attain equilibrium, the heat flow must flow form a higher temperature to a lower temperature.
(2) double covalent bond that has 4 shared electrons
(3) triple covalent bond that has 6 shared electrons
(4) triple covalent bond that has 4 shared electrons
Answers
Answer: Option (2) is the correct answer.
Explanation:
An alkene is a molecule that contains a hydrocarbon chain with atleast one double bond.
For example, is a 1-butene molecule and it contains one double bond that consists of four shared electrons.
On the other hand, a molecule of hydrocabon that contains a triple bond is known as an alkyne. Whereas a hydrocarbon that contains only single bonds is known as an alkane.
Thus, we can conclude that the multiple covalent bond in a molecule of 1-butene is a double covalent bond that has 4 shared electrons.
(2) a zinc strip and 3.0 M HCl(aq)
(3) zinc powder and 1.0 M HCl(aq)
(4) zinc powder and 3.0 M HCl(aq)
Answers
Answer:
(4) zinc powder and 3.0 M HCl(aq)
Explanation:
First consider the equation of reaction:
1 mole of Zinc requires 2 moles of HCl for reaction.
mole of zinc = mass/molar mass = 5.0/65.38 = 0.0765 mole
0.0765 mole of zinc will require: 0.0765 x 2 = 0.1530 mole HCl
Mole of 1.0 M HCl = Molarity x volume = 1 x 0.05 = 0.05 mole
Mole of 3.0 M HCl = 3 x 0.05 = 0.15
Hence, the 3.0 M HCl is what will give the required number of mole.
Zinc in powder form will react faster compared to in strip because the former has higher surface area for reaction.
Therefore, zinc powder and 3.0 M HCl will give the fastest reaction rate.
The correct option is option 4.
b. valence
c. metallic
d. covalent

I hope this helps let me know in the comments if anything is unclear.
An ionic bond is when we transfer electrons. This means that the atoms would gain a charge.
Na+Cl- would be the resulting compound because:-
Na (sodium) loses : which means it would GAIN a positive charge.
Cl (chlorine) gains: which means it GAINS a negative charge.

Answer: The mole ratio of hydrogen to ammonia is 3 : 2
Explanation:
Mole ratio is defined as the ratio of number of moles of the substances whose ratio is to be calculated.
In a chemical reaction, the stoichiometric coefficients represents the number of moles.
For the given chemical reaction of production of ammonia follows:
By stoichiometry of the reaction:
1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia.
So, the mole ratio of hydrogen to ammonia in a given chemical reaction is 3 : 2
The mole ratio of hydrogen to ammonia is 3:2.
The mole ratio of hydrogen to ammonia can be determined by examining the balanced chemical equation for the reaction:
N₂ + 3H₂ ⇒ 2NH₃
From the equation, we can see that 3 moles of hydrogen react with 1 mole of nitrogen to produce 2 moles of ammonia.
The coefficients in the balanced equation represent the mole ratio between the reactants and products. Here's a breakdown:
For every 1 mole of nitrogen, require 3 moles of hydrogen.
These 3 moles of hydrogen will react with 1 mole of nitrogen to produce 2 moles of ammonia.
