Its inorganic as MgCO3 is contains no carbon more hydrogen which is a crutial component of all organic compounds
Answer: See description
Explanation:
Kepler's laws have three principal points:
1. planets orbit the sun in elliptical paths
2. the orbial period is related to the orbital distance by 
where T is the orbital period and d is the orbital distance, T is in years and d is measured in units of the earth sun distance.
3. planets closer to the sun move faster than planets far away from it.
Newton:
Newton discovered that there is a consequence to the gravity exerted by objects: mass, the heavier the planet, the more gravitational force it posseses ( thats why we orbit the sun)
with the gravitational force
newton discovered the inverse-quadratic relationship between the distance of the planets and the acceleration exerted by the force one could exert on another.
Kepler's laws were mostly based on observed evidence with quantitative relationships between the mentioned variables. Newton's laws are based on calculus and symbolic equations. While Kepler's mode is basic, Newton took another step in and build a more general model for gravity (which was improved by general relativity later). In a nutshell Newton proved the scientific causes for Kepler's laws...
Answer:Well-known examples are sodium hydroxide (NaOH) with OH- as the polyatomic anion, calcium carbonate (CaCO3), and ammonium nitrate (NH4NO3), which contains two polyatomic ions: NH+ and NO3-. ... The properties of compounds containing polyatomic ions are very similar to those of binary ionic compounds.
Explanation:
Answer:
C) 1.3 mol
Explanation:
Using gas law we can find the initial moles of the sample of the mixture, as follows:
PV = nRT
PV / RT = n
<em>Where P is pressure: 4.0atm</em>
<em>V is volume: 9.6L</em>
<em>R is gas constant: 0.082atmL/molK</em>
<em>T is absolute temperature: 300K</em>
<em>And n are moles of the gas</em>
<em />
PV / RT = n
4.0atm*9.6L / 0.082atmL/molK300K = n
n = 1.56moles of the mixture of the gas are present into the 9.6L container
Now, 14% of this gas is hydrogen that was removed of the system, that is:
1.56mol*14% = 0.22 moles of hydrogen are removed.
Thus, moles of gas that remains in the container are:
1.56mol - 0.22mol = 1.34mol.
Right answer is:
<h3>C) 1.3 mol</h3>
