260 miles with 12 gallons of gas
260 miles/12 gallons=21.6667 miles/1 gallon
286 miles/(21.6667 miles/1 gallon)=13.2 gallons of gas
The number of atoms present, on average, will be the natural abundance of the isotope times the number of atoms in the sample => number of C-13 atoms = C-13 abundance * number of atoms in the sample = 1.07% * 30,000 = 1.07 * 30,000 / 100 = 321 atoms.<span> Answer: 321 atoms.</span>
A. 1 proton and 1 neutron
If it is a single cell then it is unicellular. it is an animal cell if it ha no cell wall and cells without nucleus are prokaryotes so it could be a Monera like bacteria.
There are four sodium atoms in the product.
A reaction equation is said to be balanced when the number of atoms of reactants are equal to the number of atoms of products according to the balanced reaction equation.
Given the reaction between sodium metal and oxygen, the reaction could be written as; 2Na(s) + O2(g) ----> 2Na2O(s). We can see that there are four sodium atoms in the product.
