Answer:
1 moles Calcium Carbonate = 100.0869 gram using the molecular weight calculator and the molar mass of CaCO3. ... How many moles Calcium Carbonate in 1 grams? The answer is 0.0099913175450533.
Explanation:
Answer:
It shows the most reactive to least reactive, so that we can predict whether certain reactions will occur. Any metal can replace any metal below it, but not above it.
Explanation:
You can use the law of superposition:in horizontal sedimentary rock,the oldest layer is at the bottom.the more layers up is younger than the ones under
There are 6.022 × 10²³ atoms in 39.948 g of argon and 4.0026 g of helium.
Explanation:
39.945 g/mole is the molar mass of argon so 39.948 g of argon are equal to 1 mole of argon.
4.0026 g/mole is the molar mass of helium so 4.0026 g of helium are equal to 1 mole of helium.
We know that Avogadro's number tell us the number of particles in 1 mole of substance which is 6.022 × 10²³.
So in 39.948 g of argon and 4.0026 g of helium contains the same number of atoms, 6.022 × 10²³.

Answer:
A. Whenever the population has increased, steel consumption has increased as well.
Explanation:
Based on the graph of US population and steel consumption, what could have led to the increase in steel consumption seen on the graph is that whenever the population has increased, steel consumption has increased as well.
A critical look at the graph, you will discover that the population and the steel consumption are moving upwards (i.e they are increasing). It's seen that as the population increases, steel consumption increases. This is true because as the population increases, people are building houses, more transportation systems that require steel are being manufactured, more household utensils that are steel products are being fabricated etc; therefore the consumption of steel increases.
