The atoms of which element will typically form ions
Musya8 [376]

Ions are electrically charged particles, meaning, that whenever any type of atom loses or gains electrons it is forming a new type of structure, or ion.

Metal atoms form postive ions, Non-Metals form negative ions.

The strongest type of bond that can occur between two ions, when they are oppositely charged, are Ionic Bonds. The most commonly known ionic bond is seen in Sodium and Chlorine, which when combined give us NaCl or Sodium Chlorine, aka Salt.

+1 charge = Group 1, Metals

+2 charge = Group 2, Alkali Metals

-1 charge = Group 17, Halogens

Provided is a periodic table marked with the charges for each group.

You are working with a specific enzyme-catalyzed reaction in the lab. You are a very careful experimentalist, and as a result, a
lord [1]

B. It will increase the rate

Explanation:

In this experiment, the rate of the reaction will increase with increase in temperature. Since enzymes are chemical catalysts that speeds up the rate of chemical reactions, one must know that a high temperature favors the rate of chemical reaction.

  • At a high temperature, the catalyst action of the enzyme will increase rapidly.
  • Caution must be taken because at extremely high temperatures, the enzymes can become denatured.

1. What number on the periodic table determines the number of electrons lost or gained?
vekshin1

Answer:

1. atomic #

2.The sugar-water is a homogeneous mixture

Explanation:

1.  However, if it has positive ion, then this electron number will go down (ie +2 charge means two electrons have been lost, so the electron/atomic number will go down by two) and vice versa.

2.Sugar dissolves and is spread throughout the glass of water. The sand sinks to the bottom. The sugar-water is a homogenous mixture while the sand-water is a heterogeneous mixture. Both are mixtures, but only the sugar-water can also be called a solution.

A military jet cruising at an altitude of 12.0kmand speed of 1900./kmh burns fuel at the rate of 74.4/Lmin. How would you calcul
anygoal [31]

Answer: amount = 2466.95L

Explanation:

given that the speed is = 1900./kmh i.e. 1hr/900km

distance = 1050km

the fuel burns at a rate of 74.4 L/min

therefore the amount of fuel that the jet consumes on a 1050.km becomes;

total fuel used = time × fuel burning rate

where time = distance / speed

∴ total fuel used (consumed) = time × fuel burning rate

total fuel consumed = (1050km × 1hr/1900km) × (60min/ 1hr × 74.4L/1min)

total fuel consumed = 2466.95L
