Answer:
Mass = 108 g
Explanation:
Given data:
Mass of water produced = ?
Number of moles of hydrogen = 6.00 mol
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Now we will compare the moles of hydrogen with water.
H₂ : H₂O
2 : 2
6 : 6
Mass of water:
Mass = number of moles × molar mass
Mass = 6 mol × 18 g/mol
Mass = 108 g
Answer:
There are three ways to make solids dissolve faster: Break the solute into smaller pieces. Stir the mixture. * Heat the mixture.
Explanation:
Substances can dissolve in water three ways—by dissociation, dispersion, and ionization.
<em>Nitric acid, </em><em>is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water.</em>
There are THREE different elements and a total of FIVE atoms in nitric acid.
<em>The formula for nitric acid is</em><em> </em><em><u>HNO3.</u></em><em> This means there is one atom of hydrogen, one atom of nitrogen, and three atoms of oxygen in one molecule of nitric acid.</em>
<em>So, Thus, your answer will be </em><u><em>FIVE</em></u><em> if you're counting the molecules but if you are counting the elements then it is </em><u><em>THREE.</em></u>

Answer:
0.0498 mol
Explanation:
Number of moles = concentration in mol/L × volume in L
Concentration = 1 M = 1 mol/L
Volume = 49.8 mL = 49.8/1000 = 0.0498 L
Number of moles = 1×0.0498 = 0.0498 mol
Answer:
Explanation:
The question is not complete, the cmplete question is:
Identify one type of noncovalent bond present in each solid.
1) Table salt (NaCl) 2) Graphite (repeating)
a. hydrogen bonds
b. ionic interactions
c. van der Waals interactions
d. hydrophobic interactions
Answer:
1) Table salt
b. ionic interactions
Ionic bond are formed between atoms with incomplete outermost shell. Some atoms add electrons to their outermost shell to make the shell complete hence making it a negative ion while some atoms loses their electron to make the outermost shell complete becoming a positive ion. In NaCl, sodium (Na) has 1 electron in its outermost shell which it transfers to Cl which has 7 electrons in the outermost shell. Hence after the bonding the outermost shell of the atoms become complete.
2) Graphite
c. Van Der Waals interaction
Van der waal forces are weak interaction between molecules that exist between close atoms. Carbon atoms in graphite planes have covalent bond, these graphite planes are known as graphenes. Bonds between graphenes are very weak and are van der waals forces.
