Among the given images, the one which is an example of non-renewable source of energy is image -1 the cooking gas is a petroleum product and it is non-renewable.
What are non-renewable energy sources?Non-renewable energy sources are sources of energy that come from finite resources that cannot be replenished on a human timescale. They are called non-renewable because their reserves are being depleted faster than they can be replenished. These energy sources include:
Fossil fuels: Coal, oil, and natural gas are the three main types of fossil fuels. They are formed over millions of years from the remains of plants and animals that lived long ago. Fossil fuels are currently the most widely used sources of energy for electricity generation, transportation, and industrial processes.
Nuclear energy: Nuclear energy is produced through the process of nuclear fission, which involves splitting atoms of uranium or plutonium to release energy. Nuclear power plants generate electricity using this process.
Non-renewable energy sources are a major contributor to greenhouse gas emissions, which contribute to climate change. As a result, there is a growing need to transition to renewable energy sources that are sustainable and have a lower environmental impact.

How many grams of copper would you need to produce 50.0g of silver? 1 Cu + 2 AgNO3 ----> 2 Ag + 1 Cu(NO3)2
how many atoms of mercury are in 50.15 g of mercury?
Answer:
please mark brainliest
Explanation:
The correct answer to this question is 0.2500 mol
Formula to calculate moles:
Moles = mass ÷ molar mass (n=m/M)
Mass = 50.15g
Atomic mass: 200.59 amu
Moles = 50.15g/200.59
= 0.2500 mol.

Why can the grasses now grow when they couldn’t earlier?
Grasses can grow where they could not earlier because the soil conditions, water volume, or rate of sunlight have evolved.
Each species of plant requires specific conditions to thrive. These conditions include:
Nutrients from the soil.SunlightSpecific amount of water.This implies that if the conditions for a specific species are not provided in terms of sunlight, radiation, and water, the plant will not grow in that specific zone. In the same way, if the conditions of a zone change and they are not suitable for a plant species the plant will grow even if this was not possible before.
This key idea is the reason why some plants including grasses can now grow in zones where they did not exist before. Some of the factors that have contributed to this are:
Fertilization: This provides soils with necessary nutrients.Climate change: This has affected climate patterns, and therefore it can increase or decrease radiation.Irrigation: This increases the amount of water available for plants.Learn more about grass in: https://brainly.com/question/3671945
Answer the following questions.
P1) Matching.
Complete the table with the data from the lab. First, calculate and enter the mole ratio in the chart, then enter the volumes of the precipitates.
The mole ratio can be seen below and the volume of each precipitate is 60 mL.
A mole ratio refers to a conversion factor that compares the quantities of two chemicals in moles in a chemical laboratory experiment.

Find the mass in kilograms of the liquid air that is required to produce 600L of oxygen. In normal condition, 1L of liquid air has 1.3g
Explanation:
1L is 1.3 g so 600L is 780 g
1kg= 1000g so
780 g = 0.78kg
I GUESS
Mass in kilograms of liquid air required = 0.78 kg
Given that
1 Litre of liquid air contains 1.3 grams of oxygen ( air )
Determine the amount of liquid air in Kg
volume of air given = 600 L
mass of liquid air required = x
1 litre = 1.3 grams
600 L = x
∴ x ( mass of liquid air ) = 1.3 * 600
= 780 g = 0.78 kg
Hence we can conclude that Mass in kilograms of liquid air required = 0.78 kg
