Which of the following is the mass in grams of 4.25 × 10³ mol of N2?
Answer:
119,059.5 g/mol
Explanation:
First, find the mass of N2
On the periodic table, nitrogen is 14.007
Because there are two nitrogens, multiply it by 2
14.007*2 = 28.014 g
Now convert... (also don't let that exponent intimidate you! You can change it to 4250 if that makes it easier)
4.25 × 10³ mol * 28.014 g/1 mol = 119059.5 g/mol

Glycerine is viscous than water?why
Answer:
Yes
Explanation:
Why is glycerol more viscous than water?
The glycerine is more viscous than water because due to presence of hydrogen atoms , we all know that glycerine has more hydrogen bonding than water molecule , which makes an aggregation which means that glycerine is more viscous than water , in simple words glycerine can't flow as that of water molecule.
How can you measure the volume of an irregular shaped solid?
Answer:
If the object has an irregular shape, the volume can be measured using a displacement can. The displacement can is filled with water above a narrow spout and allowed to drain until the water is level with the tap. As the irregular object is lowered into the displacement can, the water level rises.

1.2 billion years
4.6 billion years
6.4 billion years
8.2 billion years
Answer:
B : 4.6 billion years
Credits go to the person above me.
;)
Explanation:
EDGE 2021
The sun is about 4.6 billion years old. Therefore, option (B) is correct.
What is the sun made of?The Sun is made primarily of the elements hydrogen and helium. They account for 74.9% and 23.8% mass of the Sun in the photosphere. All heavier elements, called metals account for less than 2% of the mass, with oxygen (<1%), carbon (0.3%), neon (0.2%), and iron (0.2%) being the most abundant.
The hydrogen and helium in the Sun would have been produced by Big Bang nucleosynthesis and the heavier elements were produced by former generations of stars before the Sun was formed.
The amount of helium and its location within the Sun has gradually changed over the past 4.6 billion years. The proportion of helium has raised from about 24% to 60% due to fusion, and some of the He and heavy elements have settled from the photosphere toward the center due to gravity.
Therefore, the age of the sun is about 4.6 billion years.

if possible, can it come with an explanation pls
Answer:
An example of a combustion reaction is the burning wood in a fire.
Explanation:
In the combustion reaction, the carbohydrates in wood combine with oxygen to create water and carbon dioxide. This reaction is very energetic, and it generates heat and light as it releases said energy.

Explanation:
Using the empirical formula, calculate the formula weight of the compound. Use the periodic table to help you.
Type the correct answer in the box. Round your answer to three decimal places.
Answer:
The formula weight of the compound is
46.069 g/mol.
Explanation:
Determine the molar mass from the empirical formula (C2H6O) by multiplying the molar mass of each element in the compound by the number of atoms of it and adding the resulting masses of the elements:
molar mass of C2H6O = (2 × 12.011 g/mol) + (6 × 1.008 g/mol) + (1 × 15.999 g/mol) = 46.069 g/mol.

Think of the different types of reactions you have learned about. How can you tell if they absorb energy or release energy, and at the molecular level, how are they different?
Answer:
Absorbed will be harder to spot than releasing because take this as it's like a tire. A tire will go smaller when it has no air compared to when it has air. But absorbed it the opposite. It gets bigger with more air and etc.

A soccer player applies a force of 56.6 N to a soccer ball while kicking it. If the ball has a mass of 0.46 kg, what is the acceleration of the soccer ball?
Answer:
[tex]a=123.04\ m/s^2[/tex]
Explanation:
Given that,
Force applied to a soccer player, F = 56.6 N
The mass of the ball, m = 0.46 kg
We need to find the acceleration of the soccer ball. The force acting on the ball is given by :
F = ma
Where
a is the acceleration
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{56.6 }{0.46 }\\\\a=123.04\ m/s^2[/tex]
So, the required solution is [tex]123.04\ m/s^2[/tex].

How many moles of silver would precipitate out when 3.6 x 10^23 atoms of zinc are combined in silver nitrate according to the following unbalanced equation? (Balance equation first!)
Zn + AgNO3 → Zn(NO3)2 +Ag
A: 1.67 moles
B: 1.2 moles
C: 3.34 moles
D: 0.6 moles
Can someone please help me with this I don’t get it at all.
Answer:
D: 0.6 moles
Explanation:
First we balance the equation:
Zn + AgNO₃ → Zn(NO₃)₂ + AgThere are two NO₃ species on the right side, so we put a two before AgNO₃:
Zn + 2AgNO₃ → Zn(NO₃)₂ + AgNow we put a two before Ag on the right, to balance the Ag atoms:
Zn + 2AgNO₃ → Zn(NO₃)₂ + 2AgThe equation is now balanced.
Now we convert 3.6x10²³ atoms of zinc to moles, using Avogadro's number:
3.6x10²³ atoms ÷ 6.023x10²³ atoms/mol = 0.6 molesThen we convert 0.6 moles of zinc into moles of silver, using the stoichiometric coefficients of the balanced equation:
0.6 mol Zn * [tex]\frac{1molAg}{1molZn}[/tex] = 0.6 mol AgThus the answer is option D.
