Answer:

The scientific method is a process that can be used to answer any questions . The process begins when a scientist makes an observation. Then, they do research to learn more about the topic and write a hypothesis. The scientist will make predictions and conduct an experiment, eventually coming to a conclusion. They will share their results with other scientists to help further discovery.

Explanation:

The Scientific method is process used to observe, predict and explain phenomena around us. It involves a series of steps listed as follows:

1. Making observations: the scientist must be a keen observer of events around him

2. Ask questions: the scientist asks questions based on the observations

3. Form a hypothesis and make predictions: the scientist puts forward a reasonable explanation for the observations known as hypothesis. Predictions are then made and tested upon.

4. Experimentation: experiments are conducted to test the hypothesis and the predictions made.

5. Analysis of data and conclusion: the result of the experiments are analysed and conclusion are then drawn.

6. Communication of results: the results obtained from the experiments are then shared with other scientists to aid further research and discoveries.

What is the net ionic equation of the reaction of mgso4 with sr(no3)2?
Bad White [126]

Balanced chemical reaction:  

MgSO₄(aq) + Sr(NO₃)₂(aq) → Mg(NO₃)₂(aq) + SrSO₄(s).

Ionic reaction:  

Mg²⁺(aq) + SO₄²⁻(aq) + Sr²⁺(aq) + 2NO₃⁻(aq) → Mg²⁺(aq) + 2NO₃⁻(aq) + SrSO₄(s).

Net ionic reaction:

Sr²⁺(aq) + SO₄²⁻(aq) → SrSO₄(s).

Magnesium sulfate (MgSO₄), strontium nitrate (Sr(NO₃)₂ and magnesium nitrate (Mg(NO₃)₂) are soluble in water. Strontium sulfate (SrSO₄) is not soluble in water.

This chemical reaction is double displacement reaction - cations and anions of the two reactants switch places and form two new compounds.

A block of iron has a mass of 150 g and a volume of 20 ml. What is the density of iron? *
shtirl [24]

Answer:

<h3>The answer is 7.50 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass of iron = 150 g

volume = 20 mL

We have

density =  \frac{150}{20}  =  \frac{15}{2}  \\

We have the final answer as

<h3>7.50 g/mL</h3>

Hope this helps you

Balance this equation. If a coefficient of "1" is required, choose "blank" for that box.
Kitty [74]

Answer: 2 C2H4 + 6 O2 => 4 CO2 + 4 H2O

Explanation:The coefficient are as follows: 2: 6: 4: 4

Each atom on the reactant and product side are equal.

Reactant Product

C 2x2 = 4 4x1 = 4

H 2x4 = 8 4x2 = 8

O 6x2 = 12 (4x2) + 4 = 12
