Answer:

Amount of iron fillings in mixture = 60 mg

Explanation:

Given:

Total mass of mixture = 100 mg

Amount of salt in mixture = 10 mg

Amount of sand in mixture = 30 mg

Find:

Amount of iron fillings in mixture

Computation:

Using Law of Conservation of mass;

Total mass of mixture = Amount of salt in mixture + Amount of sand in mixture + Amount of iron fillings in mixture

100 = 10 + 30 + Amount of iron fillings in mixture

100 = 40 + Amount of iron fillings in mixture

Amount of iron fillings in mixture = 100 - 40

Amount of iron fillings in mixture = 60 mg

Can I get brainliest? It's for a challenge

Answer:

C

Explanation:

increasing the temperature will favour the forward reaction therefore the reaction system will try to counteract that by producing more heat and NO2 therefore increases the amount of products produced

increasing the pressure will favour the forward reaction as it has more moles of substance therefore if the forward reaction is favored, more product will be produced

Answer:

Li is limiting reactant

Explanation:

Based on the reaction:

6Li + N2 → 2Li3N

Where 6 moles of Li reacts per mole of N2

To solve this question we must convert the mass of each reactant to moles and using the chemical equation we can find limiting reactant

Moles Li -6.941g/mol-

1.50g * (1mol / 6.941g) = 0.2161 moles Li

Moles N2 -Molar mass:28g/mol-

1.50g * (1mol / 28g) = 0.0536 moles N2

For a complete reaction of 0.536 moles N2 are needed:

0.536 moles N2 * (6mol Li / 1mol N2) = 0.3214 moles Li

As there are just 0.2161 moles of Li

Answer:

Solid magnesium chloride is a non-conductor of electricity because the ions aren't free to move. However, it undergoes electrolysis when the ions become free on melting. Magnesium chloride dissolves in water to give a faintly acidic solution (pH = or 6).

Answer: The following side effects are common (occurring in greater than 30%) for patients taking Cisplatin:

Nausea and vomiting. Nausea may last up to 1 week after therapy.

Low blood counts.

Kidney toxicity.  

Ototoxicity hearing loss, ringing in the ears.

Blood test abnormalities (low magnesium, low calcium, low potassium)

Answer:

2-pentanone.

Explanation:

Hello there!

In this case, for the given compound and, in agreement with the octet rule, it is possible to realize that the CO is actually C=O as shown below:

CH3  -  C  -  CH2  -  CH2  -  CH3

            ||

           O

Thus, since the C=O stands for the carbonyl group within the parent chain, we infer this is a ketone and more specifically 2-pentanone as it has five carbon atoms.

Answer:

Wind energy

Explanation:

An ideal source of energy needs to be reliable, cost effective, safe and must lead to almost zero adverse environmental impact.

Wind energy is energy obtained from air moving at high velocity. This energy is harvested using windmills which convert mechanical energy to electrical energy.

Wind is inexpensive because it occurs naturally. However, a large expanse of land is required in order to mount sufficient number of windmills that will generate enough electrical energy for practical purposes.

This method of electricity generation is safe and does not lead to any environmental hazard unlike the burning of fossil fuels, use of nuclear energy or loss of habitat due to hydroelectric power generation.

Answer:

B. It undergoes a physical change.

Explanation:

Hello there!

In this case, since we know that chemical changes lead to the formation of new atoms and/or compounds due to the bonds rearrangement of the initial substances and the physical changes occur without changing the composition of the initial substances, we can infer that, since melting is a process that changes the phase of matter from solid to liquid without changing the identity of the initial substance, the answer to this question would be B. It undergoes a physical change. because the other options describe chemical changes.

Best regards!

Answer:

B. It undergoes a physical change.

Explanation:

At room temperature, the iron atoms are in an unusual loosely packed open arrangement; as iron is heated past 912 degrees Celsius, the atoms become more closely packed before loosening again at 1,394 degrees Celsius and ultimately melting at 1,538 degrees Celsius.

Answer:

Explanation:

1. HCl helps breakdown,absorb and digest food and also destroy bacterias in the stomach.

2. Organic Matter promotes good soil structure and act as reservoir of nutrients in the soil.

3. The nature of the solution is Basic

Reason... Blue litmus will remain blue in a basic solution and turn Red in an acidic solution

4. There's a number of test available for her to use but preferably... She should use the Litmus paper test. That's easier. An acidic solution will Turn a blue litmus red while the blue litmus will retain its blue color in a basic solution.

As 1 L = 1000 g

so 119 grams = 0.119000 L

Hope it is helpful to u

If yes then plz mark me brainlest

We are given:

Mass of water: 119 grams

We know that one mole of a gas occupies 22.4L of volume

Number of moles of water:

Number of moles = given mass / Molar mass

Number of moles = 119 / 18             [molar mass of water = 18 grams/mol]

Number of moles = 6.61 moles

Volume occupied:

Volume = number of moles * 22.4 L

Volume = 6.61 * 22.4

Volume = 148L

Volume (in mL) = 1.48 * 10⁻¹ mL

Answer:

C: Sodium chloride

Explanation:

Common salt is gotten when sodium atoms reacts with chlorine atoms in an exothermic reaction to form an ionic substance known as sodium chloride with the chemical formula NaCl.

Equation is;

2Na + Cl2 = 2NaCl

Looking at the options, the correct one is Sodium chloride.

Explanation:

a)

[tex]k _{sp} = [Ag {}^{ + } ][Cl {}^{ - } ] \\ but \: [Ag {}^{ + } ] = [Cl {}^{ - } ] \\ k _{sp} = [Ag {}^{ + } ] {}^{2} \\ [Ag {}^{ + } ] = \sqrt{k _{sp}} \\ = \sqrt{1.8 \times {10}^{ - 10} } \\ = 1.34 \times {10}^{ - 5} mol {dm}^{ - 3} [/tex]

b)

It has not reached equilibrium because the silver concentration is not yet equal to the value of Ksp.

c)

Yes it will dissolve in order to establish the equilibrium.
