Explanation:

An isotope is defined as the specie which contains same number of protons but different number of neutrons.

For example, $_{1}H^{+}$ is an isotope of hydrogen atom.

The number at the bottom of the symbol of an element represents the number of protons present in the atom.

So, the given atom contains only one proton and 0 neutrons. Also, when an atom is neutral in nature then it contains same number of protons and electrons.

But as the given atom has one +1 charge which means that it contains 0 electrons.

Thus, we can conclude that $_{1}H^{+}$ contains 1 proton, 0 neutrons and 0 electrons.

<h3>Answer:</h3>

H+ contains 1 proton, 0 neutrons, 0 electrons.

<h3>Explanation:</h3>

An atom is the smallest particle of an element that can take part in a chemical reaction.
Atoms are made of sub-atomic particles neutrons and protons found in the nucleus and electrons found in the energy levels.
A hydrogen atom contains 1 proton and 0 neutrons in the nucleus and 1 electron in the energy levels.
A hydrogen atom loses an electron to form an ion with 1 proton, 0 neutron and 0 electron.

How would you prepare 2.5 L of a 0.800M solution of KNO3?

statuscvo [17]

First find the mass of <span>solute:

Molar mass KNO</span>₃ = <span>101.1032 g/mol

mass = Molarity * molar mass * volume

mass = 0.800 * 101.1032 * 2.5

mass = 202.2064 g of KNO</span>₃

<span>To prepare 2.5 L (0800 M) of KNO3 solution, must weigh 202.2064 g of salt, dissolve in a Beker, transfer with the help of a funnel of transfer to a volumetric flask, complete with water up to the mark, capping the balloon and finally shake the solution to mix.</span>

hope this helps!

In an acid-base titration, a student uses 21.35 mL of 0.150 M NaOH to neutralize 25.00 mL of H2SO4. How many moles of acid are i

GalinKa [24]

Answer: There are 0.006 moles of acid in the flask.

Explanation:

Given: $V_{1}$ = 21.35 mL, $M_{1}$ = 0.150 M

$V_{2}$ = 25.0 mL, $M_{2}$ = ?

Formula used to calculate molarity of $H_{2}SO_{4}$ is as follows.

$M_{1}V_{1} = M_{2}V_{2}$

Substitute the values into above formula as follows.

$M_{1}V_{1} = M_{2}V_{2}\\0.15 M \times 21.35 mL = M_{2} \times 25.0 mL\\M_{2} = 0.1281 M$

As molarity is the number of moles of a substance present in a liter of solution.

Total volume of solution = $V_{1} + V_{2}$

= 21.35 mL + 25.0 mL

= 46.36 mL (1 mL = 0.001 L)

= 0.04636 L

Therefore, moles of acid required are calculated as follows.

$Molarity = \frac{no. of moles}{Volume (in L)}\\0.1281 M = \frac{no. of moles}{0.04635 L}\\no. of moles = 0.006 mol$

Thus, we can conclude that there are 0.006 moles of acid in the flask.

A 2.04 g lead weight, initially at 10.8 oC, is submerged in 7.74 g of water at 52.2 oC in an insulated container. clead = 0.128

QveST [7]

Answer:

Explanation:

Hello, in this case, the lead is catching heat and the water losing it, that's why the heat relation ship is (D is for Δ):

$DH_{lead}=-DH_{water}$

Now, by stating the heat capacity definition:

$m_{Pb}C_{Pb}*(T_{eq}-T_{lead}=-m_{H_2O}C_{H_2O}*(T_{eq}-T_{H_2O})\\$

Solving for the equilibrium temperature:

$T_{eq}=\frac{m_{Pb}C_{Pb}T_{Pb}+m_{H_2O}C_{H_2O}T_{H_2O}}{m_{Pb}C_{Pb}+m_{H_2O}C_{H_2O}} \\\\T_{eq}=\frac{2.04g*0.128J/(g^oC)*10.8^oC+7.74g*4.18J/(g^oC)*52.2^oC}{2.04g*0.128J/(g^oC)+7.74g*4.18J/(g^oC)} \\\\T_{eq}=51.87^oC$

Which is very close to the water's temperature since the lead's both mass and head capacity are lower than those for water.

Best regards.

What royal scientist used the 29th

olchik [2.2K]

J. Dorman probably was the scientist.

I have a question too. Can you please help me with that? I have a test tomorrow. Thank you!

1. True or False? When you charge your laptop, you are separating charges in the laptop battery.

2. True or False? When you use your laptop, the battery becomes more neutral as it runs low on power.
