'Acceleration' means any change in speed or direction
of motion.
so
C). No acceleration. Straight, at constant speed.
No change of speed or direction.
Answer:
Nonmetals are located on the upper right side of the Periodic table (see above image). Exception: Hydrogen is a nonmetal which is located on the left top corner of the Periodic table. Well, you have got the answer of “Where are Nonmetals located on the Periodic Table?”
Explanation:
<span>Answer:
Pb(NO3)2+2HCl=PbCl2+2HNO3
Step 2
Find # of moles of Pb
13.87g Pb(NO3)2 x 1 mol/331.22=.041875 mol Pb(NO3)2
Step 3
Use balanced equation to find weight of Pb(NO3)2
.041875mol Pb x 1 mol Cl2/1mol Pb x 70.90g/1 mol Cl2=2.9689g Cl2
.041875 mol Pb x 207.2/1mol Pb=8.6765g Pb
=11.65g</span>
The molarity of acetic acid is calculated as follows
find the number of moles of NaOH = molarity x volume
= 17x0.2 = 3.4 moles
write the equation for reaction
CH3COOH + NaOH = CH3COONa +H2O
since ratio is be of CH3COOH to NaOH is 1:1 the moles of CH3COOH is therefore = 3.4 moles
therefore the molarity = moles/volume
= 3.4 /10 = 0.34 M
Answer:
5.0 moles.
Explanation:
- The balanced equation of the reaction between hydrogen and oxgen to produce water is:
<em>H₂ + 1/2O₂ → H₂O.</em>
- It is clear that 1.0 mole of H₂ reacts with 0.5 mole of O₂ to produce 1.0 mole of H₂O.
∴ 2.5 mole of O₂ will react with 5.0 moles of H₂.
- The limiting reactant is O₂ and H₂ is found in excess (1.0 mole more).
From the stichiometry: 2.5 mole of O₂ will react with 5.0 moles of H₂ to produce 5.0 moles of H₂O.
<em>∴ 5.0 moles of water are produced when 6.0 moles of hydrogen gas react with 2.5 moles of oxygen gas</em>
