How many grams of lithium nitrate will be needed to make 250 grams of lithium sulfate

Answers

Answer 1

Answer: 313.03, since every molecule of lithium nitrate produces 1 lithium, where lithium sulfate consumes double, then you find that the moles of lithium sulfate are 2.27 (mass/molar mass), then multiply that by 2 (for the discrepancy in the molecule consumption/production) and then multiply that by the molar mass of lithium nitrate to find the mass of lithium nitrate needed. Hope that helped.

6. when multiplying and dividing measured quantities, the number of significant figures in the result should be equal to the number significant figures in___. a) all of the measurements b) at least and most precise measurements c) the most precise measurement d) the least precise measurement

Answers

The correct option is D.

Significant figure refers to the number of digits that are used to report a measured quantity. The amount of a significant number in a measurement always equal to the number of digits that are known with some degree of confidence and the last number, which is usually an estimate. When carrying out calculations with significant figures measurements, one must be careful to report the number of significant figure to reflect the least precise measurement.

The least precise measurement.

When figuring out how many significant figures to go to, you always use the least amount of sig figs in the question so the least sig figs means the least precise.

How can states of matter be helpful in life?

Answers

you will know that there is a long period where the temperature stays the same before any change in state of matter, and will not appear stupid in conversations

States of matter is useful in life because without solids we would have no cups shoes or tables and without liquids we wont be able to survive because we need water aka LIQUID to survive and without gases we wouldnt be able to breathe.

Do you think the saying “faster, better, cheaper” refers more to the work of a scientist or engineer? Explain

Answers

Answer:

engineering

Explanation:

when you think about the advancements in engineering over the years vs the advancements in science, engineering fits the "fast, better, cheaper" a lot more. Cars, for example, are engineered and over the years cars have been getting faster, more reliable/safe, and more affordable.

Science can also be focused on being better/more reliable/efficient, but this is mainly for things like medicine, and not science as a whole. How can "faster, better, cheaper" apply to a biologist, who studies nature?

Which of the following is the SI unit used to measure mass?

Answers

The SI unit used to measure mass is said to be option A: kilogram (kg).

What is the SI unit used to measure mass?

The kilogram (kg) is the standard unit used to measure mass. The kilogram is the main unit used to measure how heavy something is in the International System of Units. It is based on the weight of a special cylinder made of platinum and iridium called the International Prototype of the Kilogram.

The liter (b.) is the SI unit for volume, the meter (c.) is the SI unit for length, and the Kelvin (d.) is the SI unit for temperature. The kilogram is commonly used as a standard unit for measuring weight in science, industry, and everyday situations.

Hence option A is correct.

Answers

The answer is D. Decomposer

The answer is 'decomposer.'
