Answer:

demonstrated that something in the virulent s strain of pneumococcus could transform non virulent r strain bacteria into a lethal form, even when the s strain bacteria had been killed by the high temperature.

So the two experiments aim at determining the replication mechanism.

A 2.00-liter sample of a gas has a mass of 1.80 grams. what is the density ,in grams liter
maria [59]
<span>Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume.

Density = 1.80 g / 2 L = 0.9 g/L</span>

What is the density of a gas with a molar mass of 28.26 grams per mole at 3.510 ATM in 237 Kelvin​
Vikki [24]
<h3><u>Answer;</u></h3>

= 5.1 g/L

<h3><u>Explanation;</u></h3>

Using the equation;

PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.

Number of moles is 1 since one mole has a mass equivalent to the molar mass.

Therefore; We can find the volume and thus get the density.

<em>V = nRT/P</em>

<em>    = (1 × 0.08206 × 237)/3.510</em>

<em>     = 5.5408 L</em>

<em>Hence; Density = mass/volume </em>

<em>                           = 28.26 g/5.5408 L</em>

<em>                           = 5.1 g/L</em>

<em>The Density is 5.1 g/L or 0.005 g/cm³</em>

What are some properties of an ice cube that tell you it is a solid? Write at least one property, and explain
DanielleElmas [232]

Answer:

Well ice cubes are normally liquids but it is frozen water making it a solid. Since they are made of water particles, they wouldn't normally be a solid, but the particles are packed close enough together to make it one. Hope this helps! :D
