Answer:

4.21 grams of silver chloride are produced

Explanation:

Let's follow the reaction:

2AgNO₃ + BaCl₂ → 2AgCl + Ba(NO₃)₂

Ratio is 2:2 so 2 moles of nitrate produce, 2 mol of chloride.

Mol = Mass / Molar mass → 5g / 169.87 g/m = 0.0294 moles

So, 0.0294 moles of Silver chloride are produced

Molar mass AgCl = 143.32 g/m

Molar mass . mol = Mass → 143.32 g/m . 0.0294 mol = 4.21 grams

A Herbig-Haro (HH) object is:_:_________.

Phoenix [80]

Given what we know about Herbig-Haro (HH) objects, we can confirm that they are born from the collision between a jet from a star and clouds of interstellar matter.

<h3>What are Herbig-Haro (HH) objects?</h3>

To put it simply, a Herbig-Haro (HH) object is what we observe as a bright spot in distant space. Upon closer observation we can observe that these giant bright patches are not lone objects, but in fact immense groups of interstellar matter.

<h3>How Herbig-Haro (HH) objects are formed.</h3>

The formation of one of these interstellar groups requires an immense amount of energy. This energy come from the speed at which the materials that form these objects collide.
As stated in the question, the jet released from a star in the process of being born smashes into a giant cloud of dust and interstellar material to form the Herbig-Haro (HH) objects.
This collision happens at hundreds of km/s. To put it into perspective, it would be roughly 500,000 miles per hour.

Therefore, we can confirm that option b, which states, "where a jet from a star in the process of being born collides with (and lights up) a nearby cloud of interstellar matter", is the correct choice for the question pertaining to Herbig-Haro (HH) objects.

What's is the difference between relative abundance vs percent abundance

guajiro [1.7K]

Relative means you take the required amount from the actual amount which gives you the excess or abundance, its relative because you compare it to the required amount.
The percent abundance is the relative abundance as a percentage of the required amount.
Therefore % abundance= (abundance/required amount) X 100

The key difference is that percentages are standardised as a number out of 100 which allows you to compare them with other percentages without any calculations.

Hope that helps.

The number of protons in a neutral atom is balanced by an equal number of

anastassius [24]

There would be an equal amounts of ELECTRONS.

In order for the atom to be neutral it would imply that the number of protons (positive particles) and the number of electrons (negative particles) are equal since the neutrons are without charge.

Citric acid (C6H8O7) is a triprotic acid (It has 3 protons that can dissociate when dissolved) found naturally in lemon juice, a

Gnesinka [82]

Answer: The molarity of citric acid that is commercially available lemon juice is 0.416 M

Explanation:

To calculate the concentration of acid, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of acid which is $C_6H_8O_7$

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is NaOH.

We are given:

$n_1=3\\M_1=?M\\V_1=20.00mL\\n_2=1\\M_2=1.751M\\V_2=14.26mL$

Putting values in above equation, we get:

$3\times M_1\times 20.00=1\times 1.751\times 14.26\\\\M_1=\frac{1\times 1.751\times 14.26}{3\times 20.00}=0.416M$

Hence, the molarity of citric acid that is commercially available lemon juice is 0.416 M
