Explanation:
Scientists often repeat experiments multiple times.
Why is this important?
A.
Repeating an experiment helps to verify the results.
B.
Repeating an experiment turns a hypothesis into a theory.
C.
Repeating an experiment gives scientists something to do while they think of new hypotheses.
D.
Repeating an experiment allows scientists to test different variables.
Answers
Answer:
The answer is A.
Explanation:
Scientists repeat the same experiments because they wanna try to see if they keep getting the same result. When a scientific investigation is repeated, this is called replication. Replication is important in science so scientists can “check their work.” The result of an experiment is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.

Students in a chemistry class added 5 g of Zinc (Zn) to 50 g of hydrochloric acid (HCl). A chemical reaction occurred that produced zinc chloride (ZnCl2) and 6 g of hydrogen gas (H2).
Zn+ 2HCl → ZnCl2+H2
What is the mass of the zinc chloride?
Answers
Answer: 11 g
Explanation:
Zn + 2HCl → ZnCl₂ + H₂
Number of moles of Zn:
Number of moles = 5 g / 65.38 g/mol
Number of moles = 0.08 mol
Number of moles of HCl :
Number of moles = 50 g / 36.5 g/mol
Number of moles = 1.4 mol
Compare the moles of both reactant with zinc chloride:
Zn : ZnCl₂
1 : 1
0.08 : 0.08
HCl : ZnCl₂
2 : 1
1.4 : 1/2×1.4 =0.7 mol
The number of moles of zinc chloride produced by Zn are less so it will limit reactants.
Mass of zinc chloride:
Mass = 0.08 mol × 136.3 g/mol
Mass = 11 g
First you need to find the limiting reactant
n (Zn) = m/MM = 5/65.38 = 0.076 ≈ 0.08
ratio = moles/coefficient = 0.08/1 = 0.08
n(HCl) = m/MM = 50/36.45 = 1.37
ratio = moles/coefficient = 1.37/2 = 0.685
So the limiting reaction is Zn
0.08/1 = x/1
x= 0.08 moles of ZnCl2
Then u need to find the mass
m= n(MM) = 0.08 (136.28) = 10.9 ≈11

According to unit conversion, the values from smallest to largest are 10 cm, 1m,10,000mm,0.1 km.
What is unit conversion?Unit conversion is defined as a multi-step process which involves multiplication or a division operation by a numerical factor.The process of unit conversion requires selection of appropriate number of significant figures and the rounding off procedure.
It involves a conversion factor which is an expression for expressing the relationship between the two units.A conversion ratio always has value which equals to one which indicates that numerator and denominator have values which are expressed in different units.
It is an easy process which involves unit conversion between the different conversion systems. While unit conversion care needs to be taken regarding accuracy and precision.
As 0.1 km=100 m, 10 cm=0.1 m,10,000 mm=10 m and 1 m. Therefore the values from smallest to largest are 10 cm, 1 m,10,000 mm,0.1 km.

The noble gases are unreactive and stable. Which of the following explains why this is true?
They have 8 electrons in their outer shell (except for Helium).
They exist on their own without other elements.
They have more electrons than other elements.
They each have no electrons.
EXPLAIN
Answers
Answer:
The answer is A. They have 8 electrons in their outer shell (except for Helium).
Explanation: This is because of the number of valence electrons( the amount of electrons in their outer shell). For a reaction to take place, a transfer of electrons must take place. If their outer shell is already full, they don't have any tendencies to react.
Noble gases are unreactive gases and are stable. This is because they have complete octet or eight electrons in their outer shells. Thus, option A is accurate.
What are noble gases?Noble gases are the gases of the periodic table that do not show any reaction with other elements and have great stability and low reaction rates.
They are special as their outermost orbit is completely filled to complete their octet rule so they lack any free electron to take part in a chemical reaction.
Therefore, option A. noble gases have eight electrons in their outermost shell.
