What coefficient should go in front of the hydrogen peroxide (H2O2 ) molecule to make the chemical equation balanced? ___ H2O2 ➞ 2 H2O + O2
Answers
Answer:
2
Explanation:
H2O2 ➞ 2 H2O + O2
The reaction is currently not balanced because the number of atoms on the reactant side is not equal to that of the product side
Hydrogen
Reactant = 2 Product = 4
Oxygen
Reactant = 2 Product = 4
Adding 2 to H2O2 balances the reaction as the number of atoms of both elements are now balanced on both sides of the equation
2H2O2 ➞ 2 H2O + O2
Which is true of synthesis and decomposition reactions
Answers
Complete question is;
What is true of synthesis and decomposition reactions?
A) Synthesis reactions require more energy than decomposition reactions.
B) Synthesis reactions produce more products than decomposition reactions.
C) Synthesis reactions are the opposite of decomposition reactions.
D) Synthesis reactions have fewer reactants than decomposition reactions.
Answer:
C) Synthesis reactions are the opposite of decomposition reactions.
Explanation:
Correct answer is option C. This is because, Synthesis reactions are defined as those whereby substances are combined together to form larger molecules/compounds. Whereas, decomposition reactions are the opposite due to the fact that they involve the breakdown of two or more substances.
What is the correct order for the seasons of winter, spring, summer, and fall in the Northern
Hemisphere?
Answers
Answer:
Therefore, for temperate areas in the northern hemisphere, spring begins on 1 March, summer on 1 June, autumn on 1 September, and winter on 1 December. For the southern hemisphere temperate zone, spring begins on 1 September, summer on 1 December, autumn on 1 March, and winter on 1 June.
Explanation:
The correct order for the seasons of winter, spring, summer, and fall in the Northern Hemisphere is summer, spring and winter.
What is season?A season is a subdivision of the calendar year based on variations in the local climate, ecology, and amount of daylight hours. The axial parallel of Earth's inclinator orbit of the Sun causes seasons on Earth.
Seasons are distinguished by differences in the amount of sunlight reaching Earth's surface in temperate as well as polar areas. These fluctuations may lead certain animals to migrate or go into hibernation while others may cause vegetation to fall dormant. The correct order for the seasons of winter, spring, summer, and fall in the Northern Hemisphere is summer, spring and winter.
Therefore, the correct order for the seasons of winter, spring, summer, and fall in the Northern Hemisphere is summer, spring and winter.

A student need to predict the mass of a block of aluminum. The block is 4.23 cm on all sides and the density of aluminum is 2.7 g/cm3. What will the mass of the block be?
Answers
Density = mass / volume.
To rearrange for mass, you would times by volume on both sides to give you:
Mass = density x volume
Mass = 2.7 x (4.23^3)
= 2.7 x 75.686967
= 204.3548109
= 204.35 g (to 2 dp)

give two areas where the compressible nature of gas is applied
Answers
Answer:
1. Gases can be easily liquefied into very small volumes and stored in liquid form Eg in LPGA cylinders and used in homes.
2. Balloons can be easily filled with air.
The fact that a gas is easily compressible is applied in the colling devices such as air conditioners as well as in the pumping of tyres with air.
Are gases compressible?Gases are easily compressible because they do not have a definite volume. This is positively applied in many areas of life.

Which process uses the least amount of material to create electricity, coal or uranium, coal or nuclear power plant?
Answers
Answer:
nuclear power plant
Explanation:
Generation of electricity often involves the use of some kind of material or energy that is consumed as electricity is generated. There are various ways of generating electricity such as;
By burning coal
Use of a radioactive element as nuclear fuel
From wind energy
From water
From the sun, etc
Each process involves the intake of material or energy. The process that goes on in a nuclear power plant requires a radioactive fuel of which uranium is an example.
A nuclear plant uses the least amount of material (such as only 1g of uranium fuel) in electricity generation compared to the tons of coal burnt in order to generate electricity.

What happens to the pitch when the frequency of a sound wave decrease?
A it stays the same
B it decreases by that same amount
C it increases twice the amount
D it increases by the same amount
Answers
Answer:
B
Explanation:
Pitch is determined by frequency. So if frequency increases, pitch increases and produces a higher sound. If frequency decreases, pitch decreases and produces a lower sound. Frequency and wavelength are inversely related, meaning that if frequency increases, wavelength becomes shorter and vice versa

Explanation:
A ring of pure gold has a mass of 17.3 grams. How many atoms of gold are in the ring?
Answers
Answer:
5.29936 x 10^23 atoms
Explanation:
To do this, we need to find the number of moles in the ring so that we can then multiply that by Avogadro's number (6.022×10^23).
equation for finding moles: [tex]n = \frac{mass}{M_{r} }[/tex]
substitute in the known values: [tex]n = \frac{17.3}{197 }[/tex]
divide to find the value of n: 0.088 mol
Multiply by Avogadro's constant: 0.088 x 6.022 x 10^23
= 5.29936 x 10^23 atoms in the ring.
hope this helps!
According to Avogadro's number, there are 5.289×10²² atoms of gold in 17.3 grams of ring.
What is Avogadro's number?Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.
It has a SI unit of reciprocal mole whose numeric value is expressed in reciprocal mole which is a dimensionless number and is called as Avogadro's constant.It relates the volume of a substance with it's average volume occupied by one of it's particles .
According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.
Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number
In the given problem, number of atoms of gold is found out as, number of atoms=17.3/196.966×6.022×10²³=5.289×10²² atoms.
Thus, there are 5.289×10²² atoms of gold in the ring.
