Yvette conducted an experiment investigating the effects of temperature on chemical reaction time. She dropped an Alka Seltzer tablet in water of different temperatures and measured the time it took for the reaction to complete. She hypothesized that the Alka Seltzer tablet would react faster in warmer water. The Effect of Temperature on Chemical Reaction Rate: Water Temperature (°C), Trial 1, Trial 2, Trial 3, Trial 4:
10°C , 44, 46, 43, 44
20°C, 37, 39, 37, 37

science i need help please

Answers

Answer: Streak

Explanation: The color of a mineral in powdered form is called the mineral's streak. To find a mineral's streak, the mineral is rubbed against a piece of unglazed porcelain called a streak plate. The mark left on the streak plate is the streak.

The streak of a mineral is its powder's color, because streak does not vary, it is a more dependable quality than color. Minerals of the same color may have a streak of a different hue, hence option B is correct.

The streak of a mineral refers to the color of the material when it is in powdered form. A streak plate is an unglazed piece of porcelain that is used to locate a mineral's streak. The streak is the mark that was left on the streak plate.

When minerals are powdered, they often take on a distinct hue than when they are in crystal or massive form. It might be a completely different tint or a completely different color.

The property of light being demonstrated in the picture is reflection of light.

What is reflection?

Reflection of light is defined as a property of light ray that when it strikes a smooth surface it bounces back .Objects can be seen due  to this property of light.Reflection is produced by all types of waves namely sound waves, light waves, electromagnetic waves.

Reflection of light is governed by laws of reflection which are also called as Snell's laws. According to laws of reflection, angle of incidence and angle of reflection are equal.The incident ray , reflected ray and normal all lie on the same side of the plane.Light travels in a straight line before, after and during the process of reflection.There are 3 types of reflection which are diffuse reflection,specular reflection and glossy reflection.

If 12.4 mol of Ne gas occupies 122.8 L, how many mol of Ne would occupy 339.2 L under the same temperature and pressure? Record your answer in scientific notation using 3 significant figures.

Answers

Answer:

3.43×10¹ mol

Explanation:

Given data:

Initial number of  moles = 12.4 mol

Initial volume = 122.8 L

Final number of moles = ?

Final volume = 339.2 L

Solution:

The number of moles and volume are directly proportional to each other at same temperature and pressure.

V₁/n₁  =  V₂/n₂

122.8 L/ 12.4 mol  =  339.2 L / n₂

n₂ = 339.2 L× 12.4 mol  / 122.8 L

n₂ = 4206.08 L.mol /122.8 L

n₂ = 34.3mol

In scientific notation:

The effects of climate on ocean are:

A.They have warm and cool currents that affect weather on nearby land.

D.They make temperatures in nearby areas slightly milder.

Climate type of the ocean:

As ozone harming substances trap additional energy from the sun, the seas are retaining more hotness, bringing about an expansion in ocean surface temperatures and climbing ocean level. Changes in sea temperatures and flows achieved by environmental change will prompt modifications in environment designs all over the planet.

A graph with horizontal axis time (seconds) and vertical axis position (meters). An orange line runs straight upward from 0 second zero meters. A concave blue line runs upward from the same point. Maia says that both lines on this position vs time graph show acceleration. Is she correct? Why or why not?

Answers

Answer:

Let's start by using the definition of acceleration. Acceleration is defined as the change in velocity over the change in time. In equation, that would be Δvelocity/Δtime. Based on the axes of the given graph, it shows the trend of position over time. So, the slope of the line and the curve shows the change of position over change of time, Δdistance/Δtime. In physics, this is the definition of speed or velocity. So, Maia is incorrect. Both curves show the speed or velocity of the object, and not acceleration.  If the graph used a y-axis of velocity instead of position, then only at that instance, would be Maia be correct.

The difference between the two is, the straight line shows constant velocity while the curve line shows changing velocity.

Explanation:

Maria is incorrect because the line or curve shown in the graph gives value of velocity not of acceleration.

What is acceleration?

Acceleration of any object is dfine as the rate of change in velocity with respect to the distance.

According to the question, graph is plotted between time and distance so slope of the graph gives the value of change in position with repect to the time and this is used to define velocity as:

v = dx/dt

So, maria is incorrect.
