Answer:

C is the correct answer

Ethics in science are more complex than most people would think. Scientists must consider many ethical issues, including honesty, transparency, objectivity, safety and harms, and how research impacts the world. It's a lot to think about, but ethics are an important consideration for any research scientist.

If charge on only one object is tripled, determine the new force between them:

Allisa [31]

Answer:

+3·F

Explanation:

The number of objects in the given system = 2 objects

The charge on each object are; q₁ = -Q, q₂ = -Q

The force acting between the objects = +F

The distance between the objects = 2·d

The formula for the force acting between two charged particles is given as follows;

$F=K \times \dfrac{q_{1} \times q_{2}}{r^{2}}$

Therefore, we get;

$F=K \times \dfrac{-Q \times -Q}{(2\cdot d)^{2}} = K \times \dfrac{Q^2}{4 \cdot d^2}$

By tripling the charge, q₁, on the first object, we get;

q₂ = 3 × (-Q)

$F_2=K \times \dfrac{-3 \cdot Q \times -Q}{(2\cdot d)^{2}} = K \times \dfrac{3 \cdot Q^2}{4 \cdot d^2} = 3 \times +F = +3\cdot F$

Therefore, the new force between them, F₂ = +3·F

What kind of bond would form between an iron and an oxygen atom: ionic, covalent, or metallic? What kind of bond would form betw

Nostrana [21]

Answer:

See explanation

Explanation:

Since iron is a metal and oxygen is a non metal, a bond is formed between the two when electrons are transferred from iron to oxygen. Hence the bond is ionic.

Two silver atoms are held together by metallic bonds. Metallic bond are bond forces that exist between metal atoms in a crystal lattice. The valence electrons in this bond form a cloud. Metals have low ionization energy and low electronegativity hence they loose electrons easily. This accounts for the nature of the metallic bond.

The bond formed between two chlorine atoms is a covalent bond. The valence electrons in this bond are localized between the two chlorine atoms. Chlorine is a nonmetal hence it has a high ionization energy and high electronegativity. Hence it forms covalent bonds in which electrons are shared between bonding atoms.

What is the mass of 22.4L of H2 at stp

bazaltina [42]

Answer:

2.02 g H₂

General Formulas and Concepts:

Chemistry - Atomic Structure

Reading a Periodic Table
Using Dimensional Analysis
STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K

Explanation:

Step 1: Define

22.4 L H₂ at STP

Step 2: Identify Conversions

STP - 22.4 L / mol

Molar Mass of H - 1.01 g/mol

Molar Mass of H₂ - 2(1.01) = 2.02 g/mol

Step 3: Convert

$22.4 \ L \ H_2(\frac{1 \ mol \ H_2}{22.4 \ L \ H_2} )(\frac{2.02 \ g \ H_2}{1 \ mol \ H_2} )$ = 2.02 g H₂
