The total mass of the products is 10.76 g + 204.44 g = 215.20 g.
The masses of all the reactants but one are known so,
215.20 g - 120.00 g - 8.15 g - 75.00 g = 12.05 g
12.05 g is the mass of the unweighed barium nitrate.
Answer:It would never stop until something hit the ball, to slow it down.
Explanation:
This is so because there is no gravitational pull in space.
Answer: 11.0 g of calcium will react with 10.0 grams of water.
Explanation:
To calculate the moles, we use the equation:
moles of 
The balanced chemical equation is:
According to stoichiometry :
2 moles of require = 1 mole of 
Thus 0.55 moles of require=
of
Mass of 
Thus 11.0 g of calcium will react with 10.0 grams of water.
Answer:
2,3–dimethylpentane
Explanation:
To know which option is correct, we shall determine the name of the compound.
To obtain the name of the compound, do the following:
1. Determine the longest continuous carbon chain. This gives the parent name of the compound.
2. Identify the substituent group attached to the compound.
3. Locate the position of the substituent group by giving it the lowest possible count.
4. Combine the above to obtain the name of the compound.
Now, we shall determine the name of the compound as follow:
1. The longest continuous carbon chain is 5. Thus, the parent name of the compound is pentane.
2. The substituent group attached is methyl (–CH₃)
3. There are two methyl group attached to the compound. One is located at carbon 2 and the other at carbon 3.
4. Therefore, the name of the compound is:
2,3–dimethylpentane
None of the options are correct.
Passive prostheses are self-regulating, as shown in the first answer option.
We can arrive at this answer because:
- Passive prostheses are devices used to replace parts of the body that were lost by an incident.
- These prostheses are very useful to establish balance or the aesthetics of the body, but they have no articulations and no movement mechanism, being static.
This limitation allows passive prostheses not to need external regulation and to be self-regulated by fitting the body parts.
