Answer:
An atom is the smallest particle of an element that still has the properties of that element. Atoms, in turn, are composed of subatomic particles, including negative electrons, positive protons, and neutral neutrons. The number of protons in an atom determines the element it represents.
Explanation:
Answer:
Total number of atoms in glucose are 24.
Explanation:
Photosynthesis:
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
Carbon dioxide + water + energy → glucose + oxygen
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.
Chemical equation:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
Glucose molecule = C₆H₁₂O₆
Total number of atoms = 6+12+6 = 24
Types of atoms = 3 (C,H,O)
Answer:
True
Explanation:
The stoichiometry of the reaction is the proportion between the reactants and products, so it can be defined as 2:1:3:4.
With 9 cups of flor, only 8 will be used, and by the proportion, 4 eggs, and 12 oz blueberries are needed to form 16 muffins (2:1:3:4 -> 8:4:12:16). So, if there are 4 eggs and plenty of blueberries, 16 muffins can be produced.
the gas is identified as follows
by use of ideal gas equation that is PV = nRT where n is number of moles calculate the number of moles involved
P= 507 torr
R(gass constant) = 62.364 L.torr/K.mol
T= 97 + 273 = 370 k
V = 500ml = 500/1000= 0.5 Liters
by making n the subject of the formula n = PV/RT
= (507 torr x0.5 L)/ 62.364 L.torr/Mol.k x 370 k) = 0.011 moles
the molar mass of the gas = mass/ number of moles
= 0.966/0.011= 88 g/mol = the gas is therefore Krypton since 88 g/mol is one of the isotope of krypton
Answer:
7.208 g
Explanation:
0.4mol x 
= 7.208 g
You are using molar mass of H20 to find the mass. Moles of 0.4 and 1 mol cancel out leaving you with just grams. You get the values in the numerator from the periodic table and the 2(1.01) is because you have 2 of the H in H20
