Answer 2

Stars in the sky appear to be moving. We call this conclusion that is based on observations, clues, or evidence is Inference.

What is inference?

An inference is a conclusion that we can make when we have seen evidences of some particular situations and according to that we give statements.

For example-

1. If someone made a bad face just after taking a bite of food then we can infer that the person didn't like the food.

2. If someone is going away from a place after another person arrived then we can infer that the first person doesn't like the second person.

3. If someone is very lazy from the beginning of the day then we can infer that the person didn't take proper rest.

Given options are-

A. Hypothesis

B. Inference

C. Procedure

D. Report

Therefore, Stars in the sky appear to be moving. We call this conclusion that is based on observations, clues, or evidence is Inference.

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

The answer is 11
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

Answers

Answer: it has ice in it and that makes the things you use with the cold pack colder

Answer:

When the inner bag of water is broken by squeezing the package, it dissolves the solid in an endothermic reaction. This reaction absorbs heat from the surroundings, quickly lowering the pack's temperature.

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.

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.
