What is the relationship between mass and weight?

Chemistry
1 answer:
zimovet [89]3 years ago

I believe it is

D) weight is the effect of gravity in mass

Because Mass is a measure of how much matter an object contains, while weight is a measure of the force of gravity on the object.

HELP PLS !!!! :))Formula unit of Sr and CI<br><br> Formula unit of AI and S
xenn [34]

Answer : The formula unit of Sr & Cl is SrCl_2 and the formula unit of Al & S is Al_2S_3

Explanation :

Formula unit : it is defined as the lowest number ratio of ions of an elements in an ionic compound or covalent compound.

For the formula unit of Sr & Cl, two chloride ions(Cl^-) are needed to neutralize the one strontium ion(Sr^{2+}).

For the formula unit of Al & S, three sulfide ions(S^{2-}) are needed to neutralize the two aluminium ion(Al^{3+}).

The formula unit of SrCl_2 and Al_2S_3 are shown below.

The fact that same molecules of matter have been around for years is supported by​
Elza [17]

Answer:

The law of definite proportions

Explanation:

The law of definite proportions states that atoms combine in a molecule in a specific molar ratio or specific stoichiometry. For example, it's proved that regardless of the quantity we take, two hydrogen atoms always combine with one oxygen atom to form a water molecule.

Similarly, ionic substances follow the same pattern. Since the net charge of ionic salts should be equal to 0 and each element has a definite number of valence electrons in its shell all the time, the ions combine in a way, so that cations balance the charge of anions.

Essentially, the law of definite proportions is applicable and will be applicable in the future, since we know that each element has a fixed number of valence electrons in its ground state.

Which compound contains both ionic and covalent bonds?
slava [35]
<span>Answer is </span>(3) - Sodium Nitrate.<span>

</span>Normally ionic bonds can be seen between metals and non-metals while covalent bonds present between non-metals. Another thing that determines the bond nature is electronegativity value of the atoms. If the electronegativity difference is high, then that bond tends to be an ionic bond.<span>
 
</span><span>Sodium nitrate consists of </span>Na⁺<span> and </span>NO₃⁻ ions. Hence, the bond between Na⁺ and NO₃⁻<span> is an </span>ionic bond. <span><span>

NO</span>₃⁻ </span><span>is made from </span>N <span>and </span>O<span>. Both are </span>non-metallic atoms. <span>The </span>electronegativities <span>of </span>N <span>and </span>O <span>are </span>3.0 <span>and </span>3.5 <span>respectively. Hence, there is </span>no big difference between electronegativity values (3.5 - 3.0 = 0.5<span>). Hence, the bond between N and O is a </span><span>covalent bond. </span>

Read the following chemical equation: Ti + 2Cl2 → TiCl4 Which statement best identifies and describes the reducing agent in the
goldenfox [79]

Answer: Ti is the reducing agent because it changes from 0 to +4 oxidation state.

Explanation:

  • Firstly, we need to identify the reducing agent and the oxidizing agent.
  • The reducing agent: is the agent that has been oxidized via losing electrons.
  • The oxidizing agent: is the agent that has been reduced via gaining electrons.
  • Here, Ti losses 4 electrons and its oxidation state is changed from 0 to +4 and Cl₂  gains one electron  and its oxidation state is changed from 0 to -1.
  • So, Ti is the reducing agent because its oxidation state changes from  0 to +4.
  • Cl₂ is the oxidizing agent because its oxidation state changes from 0 to -1.
  • Thus, The right answer is Ti is the reducing agent because it changes from 0 to +4 oxidation state.
