Answer:
135.0 g
Explanation:
the block read 100, 30, and 5 putting those together makes 135.00 g
Answer:
8 GRAMS OF OXYGEN WILL BE REQUIRED TO PRODUCE 9 GRAMS OF WATER MOLECULES.
Explanation:
The equation for the reaction is;
2 H + O2 ----> 2 H2O
(H = 1, O = 16)
From the reaction, it can be observed that 1 mole of O2 reacts to form 2 moles of H2O
At STP, using the molar masses of the elememts and compound in the reaction, 32 g of O2 will reacts to form 36 g (18 * 2 g) of H2O
32 g of O2 = 36 g OF H2O
if 9 grams of H2O is produced, the mass of oxygen required to produce it will be:
( 32 * 9 / 36 ) g of O2
= (288 / 36) g
= 8 g of O2
So, 8 grams of Oxygen will be required to produce 9 grams of water.
Answer:
(a) 4p: ml = -3, -2, -1, 0, +1, +2, +3
(b) 3d: ml = -2, -1, 0, +1, +2
(c) 2s: ml = -1, 0, +1
(d) 5p: ml = -4, -3, -2, -1, 0, +1, +2, +3, +4
Explanation:
Manetic quantum numbers determine the spatial orientation and number of orbitals in the subshell. ml is from -l to +l.
Answer: Yes. That is right. The actual answer, not rounded, would be 12.7778 Degrees Celsius.
Answer:
There are two sets of groups in the periodic table. The first set are Group A elements and are also known as representative elements. The second set are Group B elements and are also known as transition metals. Representative elements are the most abundant elements on earth.
