The correct answer is Heterogeneous Mixture

Explanation:

In chemistry and related fields, a mixture refers to a substance that is composed of two or more substances. This is the opposite of a pure substance that has not been combined with others. In the case of the vegetable soup, this is a mixture because it integrates multiple substances such as water, salt, vegetables, etc.

On the other hand, a mixture is classified as homogeneous if the elements are completely integrated, and the final substance is uniform or as heterogeneous if the mixture is not uniform. In the case of the soup, this can be classified as a heterogeneous mixture because in most cases you can identify the elements in it such as pieces of vegetables and therefore it is not a uniform or homogeneous mixture.

What type of chemical bond forms between positive and negative ions? (1 point)?
vlada-n [284]

Ionic bond is formed between positive and negative ions.

Positive ion is known as cation (electropositive metal)

Negative ion is known as anion ( electronegative non-metal)

The bond formed between a metal (positive ion) and non-metal (negative ions) is known as Ionic bond.

Ionic form is formed when one or more electrons from the valence shell of an atom (electropositive metal ) are completely transferred to the valence shell of another atom (electronegative non-metal). Ionic bonding is the complete transfer of valence electron(s) between oppositely charged atoms.

For example: Bond between NaCl(sodium chloride) is an ionic bond in which Na (sodium ) is positive ion(metal) which have +1 charge and Cl (chlorine) is negative ion(non-metal) which have -1 charge and the bond formed between Na+ and Cl- is ionic bond.

Na^{+}(positive ion) + Cl^{-}(negative ion)\rightarrow Ionic bond

When 5.467 grams of compound z are burned in excess oxygen, 15.02 grams of co2 and 2.458 grams of h2o are produced. determine it
Vera_Pavlovna [14]

Given the mass of CO2 =15.02 g

Moles of CO_{2}=15.02 gCO_{2} *\frac{1 molCO_{2} }{44.01 gCO_{2} } =0.341 mol CO_{2}

Mass of H2O = 2.458 g

Moles of H_{2}O=2.458 g H_{2}O*\frac{1molH_{2}O }{18.02g H_{2}O } =0.136molH_{2}O

Moles of C = 0.341 mol CO_{2}*\frac{1 molC}{1 molCO_{2} }  =0.341molC

Moles of H = 0.136 mol H_{2}O * \frac{2 mol H}{1 mol H_{2}O } =0.272 mol H

Mass of C in the sample = 0.341 mol C*\frac{12.01g C}{1 mol C} =  4.095 g C

Mass of H = 0.272 mol H *\frac{1.01 g H}{1 molH}=0.275 gH

Mass of O in the sample = 5.467 g - (4.095 g +0.275 g) = 1.097 g O

Moles of O = 1.097 g O * \frac{1 molO}{16 g O} =0.0686 mol O

Simplest mole ratios of the elements in the compound:

Cx_{\frac{0.341mol}{0.0686mol}} H_{\frac{0.272mol}{0.0686mol} }O_{\frac{0.0686mol}{0.0686mol} }

Therefore the empirical formula of the compound is C_{5}H_{4}O

Which of the following elements is the smallest?
Oliga [24]

Answer:

Explanation:

The atomic radius of elements are used to estimate the sizes of elements. The atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state of metals.

To solve this problem we will obtain the atomic radius values of the given elements from a standard atomic radius table;

          Si          111 pm

           P          98 pm

          Cl          79 pm

            S           87pm

pm = picometer

We see that chlorine has the least atomic radius
