Answer:
The answer to your question is
Explanation:
Data
12.5 g of reactant
Balanced Reaction 1
TiBr₄ + 2H₂ ⇒ Ti + 4HBr
Molar mass of TiBr₄ = 48 + (4 x 80) = 368 g
Atomic mass of Ti = 48 g
Molar mass of HBr = 1 + 80 = 81
368 g of TiBr₄ ---------------- 48 g of Ti
12.5 g of TiBr₄ -------------- x
x = (12.5 x 48) / 368
x = 1.63 g of Ti
368 g of TiBr₄ ----------------4(81) g of HBr
12.5 g of TiBr₄ ------------- x
x = (12.5 x 324) / 368
x = 11 g of HBr
Balanced reaction 2
3SiH₄ + 4NH₃ ⇒ Si₃N₄ + 12H₂
Molar mass of SiH₄ = 28 + 4 = 32
Molar mass of Si₃N₄ = 28 x 3 + 14 x 4 = 84 + 56 = 140 g
Atomic mass of H₂ = 2 g
3(32) g of SiH₄ --------------- 140 g of Si₃N₄
12.5 g of SiH₄ -------------- x
x = 18.2 g of Si₃N₄
3(32) g of SiH₄ --------------- 24 g of H₂
12.5 g of SiH₄ -------------- x
x = 3.125 g of H₂
Answer:
D. Grass
Explanation:
Every living organism must contain one or more cells to be considered "living". Each cell, however, contains certain structures that perform specific roles called ORGANELLES. These organelles are of different types and hence, perform different tasks. For example, mitochondria is the power house of a cell i.e. site of energy production, and hence, is found in every eukaryotic cell.
On the other hand, chloroplast is an organelle designed to perform photosynthesis, which only occurs in plant cells. Since only plant cells can undergo photosynthesis, only plant cells can contain chloroplast. Hence, according to this question, GRASS as a type of plant is an organism that will contain both mitochondria and chloroplast in its cells.
Answer:
cesium
Explanation:
The most reactive metal on the periodic table is francium. However, francium is a man-made element and only minute quantities have been produced, so for all practical purposes, the most reactive metal is cesium. Cesium reacts explosively with water, though it is predicted francium would react even more vigorously.
Hi.
I did some digging and I think I found what you're looking for.
I found this on Q(uizlet)
basic or acidic conditions and the reactants must be heated.
