A student designs an experiment to see the effects exposing a block of ice to sunlight over time. The students makes a hypothesi
jeka94

In this experiment, the experimental group is ice, the independent variable is sunlight while on the other hand, the dependent variable is block of ice.

<h3>What are dependent and independent variables?</h3>

Dependent variable is a type of variable in which a variable whose value depends on another variable while on the other hand, independent variable is a type of variable in which a variable whose value does not depends on another variable. Dependent variable is denoted by X whereas the independent variable is denoted by Y.

So we can conclude that In this experiment, the experimental group is ice, the independent variable is sunlight while on the other hand, the dependent variable is block of ice.

Bicarbonate concentrate mixers may have a which are replaced on a routine basic.
Sidana [21]

Answer: True the bicarbonate mixture can help save time and few routine.

Explanation:

For the purpose of making dialysate for hemodialysis patient therapies a bicarbonate mixing and delivering systems designed to prepare a liquid sodium bicarbonate formulation comes in handy.

Certain systems like the SDS unit also allow for the transfer and distribution of acid concentrate solutions. We also provide stand-alone acid concentrate delivery systems using a variety of holding tanks and delivery methods. 

A challenge for hemodialysis providers is to properly provide bicarbonate solution in a cost effective manner. Preparation and disinfection can be time-consuming and labor intensive.

Bicarbonate however can corrode certain metals and painted surfaces leaving your preparation area encrusted and grimy.

Furthermore, if not mixed properly, bicarbonate can negatively affect the dialysate solution.

The answer to the above is true the bicarbonate mixture can help save time and few routine.

What does the space-filling model of a water molecule tell you about the relative size of the atoms?
faltersainse [42]
Space -filling models are also known as Calotte models. These are 3 dimensional models that depict the spatial relationships between atoms.
The space-filling model of water molecule shows the 3 D structure of the water molecule. This model CLEARLY REVEALS THE OXYGEN ATOM WHICH IS LOCATED CENTRALLY WITH TWO HYDROGEN ATOMS IN THE ADJACENT SIDES. THE MODEL ALSO SUGGESTS HOW THE WATER MOLECULES ATTRACT EACH OTHER.
